Эти формы помогают сказать, что для тебя подходит почти любой вариант.

Because формы is plural here.

• этот = this (masculine singular)
• эта = this (feminine singular)
• эти = these (plural)

Since формы means forms and is plural, you need эти:

• эта форма = this form
• эти формы = these forms

Also, форма is feminine in the singular, which is why the singular would be эта форма.

Because its subject is эти формы, which is plural.

In Russian, the verb agrees with the subject in number:

• эта форма помогает = this form helps
• эти формы помогают = these forms help

So помогают is the 3rd person plural form of помогать.

This is a very common Russian pattern:

• помогать + infinitive = to help (someone) do something

So:

• формы помогают сказать = the forms help (you) say

The infinitive сказать tells you what the forms help you do.

Compare:

• помогает понять = helps (someone) understand
• помогают объяснить = help (someone) explain
• помогают сказать = help (someone) say

Because сказать usually means to say / to express something конкретely, while говорить often means to speak / to talk / to say in a more general sense.

Here the idea is that these forms help you say a specific thing. That fits сказать well.

Very roughly:

• сказать = to say, to state, to express once
• говорить = to speak, to talk, to be saying, to speak generally

So помогают сказать, что... sounds natural because it means help you say that...

Here что means that and introduces a subordinate clause.

So:

• помогают сказать, что... = help (you) say that...

The clause after что is:

• для тебя подходит почти любой вариант

So the structure is:

• These forms help say that almost any option suits you / works for you.

This is a very common Russian pattern:

• Я думаю, что... = I think that...
• Он сказал, что... = He said that...
• Помогают сказать, что... = They help say that...

Тебя is in the genitive case because it comes after the preposition для.

• для = for
• для + genitive

So:

• для меня = for me
• для тебя = for you
• для него = for him

In this sentence, для тебя means for you.

Because the subject of подходит is почти любой вариант, and that whole phrase is singular.

The key noun is:

• вариант = option / variant

And it is singular here. So the verb must also be singular:

• вариант подходит = the option suits / works
• варианты подходят = the options suit / work

Even though любой means something like any, the phrase любой вариант is grammatically singular: any one option.

Because вариант is the subject of the verb подходит.

Russian uses a different structure from English here. Instead of saying:

• something suits you

Russian often says literally:

• something fits/is suitable for you

So in:

• для тебя подходит почти любой вариант

the thing doing the “fitting/suiting” is почти любой вариант, so it stays in the nominative.

Compare:

• Этот вариант подходит мне. = This option suits me / works for me.
• Любой вариант подходит тебе. = Any option suits you / works for you.

Its basic meaning is related to fit / suit / be suitable / work.

The verb подходить can mean:

• to approach
• to fit
• to suit
• to be appropriate

In this sentence, it means:

• to suit
• to work for
• to be suitable for

So:

• для тебя подходит почти любой вариант = almost any option works for you / suits you

This is a very common use of подходить:

• Мне это не подходит. = This doesn’t work for me.
• Какой цвет тебе подходит? = What color suits you?
• Этот вариант нам подходит. = This option works for us.

Yes — тебе подходит is also very natural, and in many situations it is actually more common.

You can say:

• для тебя подходит почти любой вариант
• тебе подходит почти любой вариант

Both can mean almost any option suits you / works for you.

The version with для тебя can feel a bit more explicit or emphatic: for you.
The version with тебе uses the dative case directly with подходить, which is extremely common.

So a learner should know both patterns:

• что-то подходит кому-то = something suits someone
• что-то подходит для кого-то = something is suitable for someone

It means almost any option.

Breakdown:

• почти = almost
• любой = any
• вариант = option / variant

Grammar:

• вариант is masculine singular nominative
• любой matches it in gender, number, and case
• почти is an adverb and does not change

So:

• любой вариант = any option
• почти любой вариант = almost any option

Often, yes, but not always perfectly.

In this sentence, любой вариант means:

• any option
• pretty much any option
• whichever option

The idea is that there are many possible options, and nearly all of them would suit the person.

So почти любой вариант means that the range is very broad: almost any option will do.

Not completely. Russian word order is more flexible than English word order, although different orders can change emphasis.

The given sentence is natural:

• Эти формы помогают сказать, что для тебя подходит почти любой вариант.

But you might also see or hear:

• Эти формы помогают сказать, что почти любой вариант подходит для тебя.
• Эти формы помогают сказать, что почти любой вариант тебе подходит.

These versions are all understandable, but the exact nuance and emphasis can shift a bit.

A useful rule for learners:

• Russian word order is often used for focus and emphasis, not just grammar.
• But agreement and case endings still tell you who is doing what.

In this context, формы most likely means grammatical forms.

Russian форма can mean:

• form
• shape
• grammatical form

Since the sentence says These forms help say that..., it strongly suggests some kind of language-learning context, where certain forms let you express the idea that almost any option suits you.

So here формы probably means something like:

• grammatical patterns
• word forms
• language forms used to express this meaning
