Can someone explain this please?

There's two ways one might examine this construction: 1) As a subjunctive-verb construction. *e.g., sees* becomes *see.* 2) As an elided auxiliary-verb construction. *e.g., He suggested that she (should) see a doctor.*

It's [the subjunctive mood](https://en.wikipedia.org/wiki/English_subjunctive). It expresses things that are hypotheticals, wishes, and wants. These are things that are not certain or facts. "He suggested that she *see* a doctor" has the same thing going on as "If I *were* a rich man..." and not "If I was a rich man..."

English has these echoes of the subjunctive all over it, even though most English speakers have no idea what that even means. As it is in romance languages, it describes doubt, as in something is asserted even though it may not actually happen. "He told us that she sees a doctor." He let us know that she for a fact visits the doctor. "He suggested that she see a doctor." He let us know she should see a doctor, *but it's doubtful that she does.* Honestly, this may be about the only place the subjunctive is pretty consistently used. Here's a case where it isn't: "If I was to see a doctor..." versus "If I were to see a doctor..." Because *were* is only used in the subjunctive for the the first person *I,* a lot of English speakers will instead use *was*, the preterite form. Were is the "technically correct" option. One last goofy thing: "If not for," "save for," and similar phrases are also subjunctive phrases. That use of *for* implies the same doubt principal as all the previous examples. They often prompt *would*, which serves as both the past tense and subjunctive form of *will*.

gonna be honest, as a native speaker, I can understand the difference, but it's so unbelievably tiny and unnoticeable that I don't know how to explain it to you. i think you should view this as unimportant to learn. both should be accepted generally. i think the only time this could ever matter is on a college essay. in fact, it took me probably 20 seconds thinking of why the heck you were being flagged wrong. so again I suggest ignoring it

I'm not a native but what I can understand from it is that s only comes after the verb when it is in present form. It is an indirect sentence and is in past (the reporting speed: suggested). An easier example to understand it would be "He suggested that she *should* see a doctor". Just want to hear if I'm wrong here by the natives, there might be some case that I'm missing. Edit: Just saw another guy also use 'should' to explain it.

They both work. See sounds better. But I’ve heard both.

I would find the sentence even more natural if it were: "He suggested that she should see a doctor", with the word should there.

what app is this?

Sorry but what’s that app?

Wouldn't sees also be correct, but meaning that he suggested that she does see a doctor?

"He suggested that she sees a doctor," could be rephrased as, "When we spoke, he implied that she sees a doctor, but he didn't outright tell me so." Whoever she is, she has some kind of medical condition that became apparent to me. So, whoever he is, he told me that she is seeing a doctor - probably regularly - for that medical condition. "He suggested that she see a doctor," could be rephrased as, "He told her to go to the doctor." In this case, she is displaying or discussing medical symptoms that she has not spoken to a doctor about. He is suggesting that she go talk to a doctor, as the symptoms are beyond the range of remedies you can get from just talking to friends, family, or acquaintances. The second sentence is used more often. So, the AI/program giving you suggestions urged you to switch to it. Only you know if what you meant actually follows its suggestions. I'm going to tell you right now that for me, a native speaker, those kinds of programs have always only ever been an annoyance. Aside from very basic things (like whether or not a word is spelled correctly), they're as likely to be wrong as right. The more complicated your sentences get, the more likely it is that the machine misunderstands what you're trying to say and "corrects" you into making an error. I'll grant that they're better than they used to be, but I wouldn't put all that much stock in them.

what’s that app?

He suggested her to see a doctor

The recommended action (a verb) needs to be subjunctive in this case, meaning there is no "s." It is similar in a sentence like "I asked that he be quiet."

Subjunctive moods

I recently read similar cases from *A Student's Instruction to English Grammar*, which illustrates a useful method, the *substitution test* (on p. 48), for dealing with such cases, as [the most upvoted answer](https://www.reddit.com/r/EnglishLearning/comments/1ih8pib/comment/mav6c2f/) did. For example, you can replace the "that ..." part with *He suggested that you* ***be*** *careful*, while the incorrect counterpart *He suggested that you* ***are*** *careful* sounds bizarre and is ungrammatical. My understanding of the slight difference is that sentences like *you are careful* or *she sees a doctor* are used to describe a fact, while in suggestions the situation described in the "that ..." part is simply not the fact, but something is not happening and will happen if the suggestions are followed. Edit: The book also mentions on p. 45 that: >many speakers would here use the present tense in preference to the slightly more formal subjunctive So I guess *He suggested that she sees a doctor* may be correct in some dialects.

This is the subjunctive.

I find this funny as the correction changes the meaning of the sentence. Since I don't know the actual intent, most of the analysis done so far is speculation. In the construct he suggests the she see a doctor. The meaning is the person should make a doctor's appointment to visit them. In the construct he suggests the she sees a doctor. The meaning could very well be that a person views anothet person in a white lab coat and stethescope and is confused. The suggestion is about what the person views. No way of determining which is correct

There's a good chance that your native language has a similar structure. In this case, "see" is in infinitive, because that is not an active act of seeing, but a suggestion to go see a doctor.

UK speaker here. I honestly wouldn't notice the difference, and take the same meaning from both. It comes across as quite a formal sentence these days anyway that you would rarely hear in everyday speech.

In English, the subjunctive mood is used to express suggestions, demands, or hypothetical situations. In the sentence "He suggested that she see a doctor," the verb "see" is in the subjunctive form, which is identical to the base form of the verb. This is why "see" is used instead of "sees. The subjunctive is often used after verbs like "suggest," "recommend," or "demand," and it remains the same regardless of the subject. Want to test your English skills in a fun way?

It's the Present Subjunctive tense; technically correct, but not widely used by native English-speakers these days in this context

She sees, is present. that she see, is subjunctive. For me the implication is that she should GO see, but I also grew up speaking this insane language so that may add a layer to any confusion

You've discovered the subjunctive! It's almost entirely unnoticeable in English, but this is one of the places it pops up!

I can't explain why it's this way, but even as a native speaker this one confused me for a few seconds. It's a difficult one, don't worry too much about making that mistake.

I hate the subjunctive mood, I hate the subjunctive mood, I hate the subjunctive mood.

Either could be correct, depending on intent. It could mean "He (Fred) suggested (to Tom) that she (Emily) sees a doctor (for on-going treatment). Or "He (Fred) suggested (to Emily) that she (Emily) see a doctor (for that uncomfortable ingrown toenail). If it's not clear from context, rewrite it to make it clear.

Subjunctive

‘Sees’ would be extremely natural in speech where Im from, and in several forms of that sentence is what Id use, but Id recommend just going with ‘see’. Other comments explained the reason behind it well :)

The main reason it might seem normal is because I have heard and said something similar, it is improper grammar that people use a lot Same with how many people just type “your” regardless if it is “you’re” or “your”

He suggested that she <should, in the future> see a doctor.

It's a suggestion. It's like saying: "I suggested that he do his homework." Or: "I suggested that he does his homework." The first sounds like he's telling the other what to do; the second sounds like he's stating what he thinks the other is already doing. Cool?

Yeah this is when l stopped paying attention in 7th grade. Props to the people that explained this so well.

She sees a doctor - she can currently meet with a doctor She see a doctor - that she will plan on meeting with the doctor in some future time

tbh, this is one of those cases where enough native english speakers would use either that i would be pretty comfortable calling both correct, especially if you're accounting for different dialects. though it really depends on whether you're making a prescriptive or descriptive case for grammar
