אם אין לך מה להוריד עכשיו, תעזרי לי לבחור גרסה טובה יותר.

אם means if here. It introduces a condition:

אם אין לך מה להוריד עכשיו = If you don’t have anything to download right now

Hebrew uses אם very commonly for conditional sentences, just like English uses if.

In Hebrew, possession in the present tense is usually expressed with יש ל־ and אין ל־:

• יש לך = you have
• אין לך = you don’t have

Literally, it is closer to there is / there isn’t to you.

So:

• אין לך = you don’t have
• אין לי = I don’t have
• אין להם = they don’t have

This is one of the most basic and important Hebrew patterns.

Normally, yes: מה means what.

But in the pattern יש/אין + ל־ + מה + infinitive, it often means something/anything to... or, with אין, nothing to....

For example:

• יש לי מה לאכול = I have something to eat
• אין לי מה לומר = I have nothing to say
• אין לך מה להוריד = you have nothing to download

So even though it literally looks like what to download, the natural English meaning is anything to download or nothing to download, depending on the sentence.

The basic meaning of להוריד is to lower, to take down, or to remove.

But in modern Hebrew, especially in technology contexts, it also very commonly means to download.

So in this sentence, להוריד almost certainly means to download.

Context is what tells you which meaning is intended.

עכשיו means now or right now.

In this sentence it modifies the idea of downloading:

אין לך מה להוריד עכשיו = you don’t have anything to download right now

Its position is very natural in Hebrew. Hebrew word order is somewhat flexible, but this placement sounds normal and neutral.

This is a very common point for learners.

The traditional imperative of לעזור to one woman is עזרי.

But in modern spoken Hebrew, people very often use the 2nd-person future form as a command instead. So:

• עזרי לי = traditional / more formal / more literary
• תעזרי לי = very natural in everyday speech

So תעזרי לי is a normal colloquial way to say help me when speaking to one woman.

Because of תעזרי.

The ending ־י here marks second-person feminine singular. So the sentence is addressed to one female.

The word לך does not help much in normal unvocalized writing, because לך can represent either masculine or feminine to you. The verb is what makes the gender clear.

Hebrew usually does not need an explicit subject pronoun when the verb already tells you who the subject is.

So:

• תעזרי already means you (feminine singular) help / will help
• there is no need to add את

If you did add את, it would usually sound emphatic, like you help me or you, help me.

Hebrew often uses this structure:

לעזור ל־מישהו + infinitive

That means:

to help someone do something

So here:

• לי = me
• לבחור = to choose

Together:

תעזרי לי לבחור = help me choose

A few similar examples:

• תעזור לי להבין = help me understand
• תעזרי לי למצוא = help me find

So לי is the person receiving the help, and לבחור is the action.

Yes, both are possible.

The standard comparative pattern in Hebrew is often:

adjective + יותר

So:

• טובה יותר = better
  literally: good-more

Since adjectives usually come after the noun in Hebrew, you get:

גרסה טובה יותר = a better version

You may also hear:

גרסה יותר טובה

That is common in speech too, but גרסה טובה יותר sounds a bit more standard and polished.

Only the forms that depend on the person addressed need to change.

To one man:

אם אין לך מה להוריד עכשיו, תעזור לי לבחור גרסה טובה יותר.

To more than one person:

אם אין לכם מה להוריד עכשיו, תעזרו לי לבחור גרסה טובה יותר.

So the key changes are:

• תעזרי → תעזור for one male
• לך → לכם and תעזרי → תעזרו for plural
