ברגע שנמצא סימן שחיקה, נבדוק אם הבגד לביש.

Yes. Literally, ברגע means in the moment, but ברגע ש־ is a common expression meaning the moment that, as soon as, or once.

So ברגע שנמצא... means something like as soon as ... is found.

Compared with כש־ or כאשר, ברגע ש־ often sounds a bit more immediate.

Because ש־ is a short attached particle. It usually sticks directly to the next word.

Here:

• ש־ = that / when
• נמצא = is found / found

So שנמצא is literally that-is-found or when-is-found, depending on context.

This is very normal in Hebrew:

• כשנגיע = when we arrive
• שאמרתי = that I said
• שנמצא = that is found / when it is found

נמצא comes from the root מ־צ־א and is in נפעל.

In unpointed Hebrew, נמצא can be ambiguous. It can mean:

• was found
• is found
• sometimes, by context, something like is detected

Here the intended sense is passive and general: a sign of wear is found.

So the sentence is not talking about one specific past event. It is describing a procedure: whenever such a sign is found, we check the garment.

You definitely could say ברגע שיימצא סימן שחיקה. That would sound more explicitly future-oriented: the moment a sign of wear will be found / is found.

But Hebrew often uses less explicit forms in procedural or general statements, especially when the context already makes the sequence clear. Since the next verb is נבדוק (we will check), the meaning is already understood as future/procedural.

So:

• ברגע שנמצא סימן שחיקה = natural in a procedural/contextual sense
• ברגע שיימצא סימן שחיקה = more explicitly future

סימן שחיקה is a construct chain (called סמיכות in Hebrew).

It literally works like:

• סימן = sign
• שחיקה = wear
• together: sign of wear

Hebrew often expresses X of Y by putting two nouns together, without של.

So:

• סימן שחיקה = a sign of wear
• not necessarily סימן של שחיקה

Using של is sometimes possible in Hebrew, but here the construct form is the normal, compact, idiomatic choice.

Here שחיקה means wear, abrasion, or deterioration from use.

With clothing, it refers to physical damage from repeated use, friction, washing, age, and so on.

A learner may have seen שחיקה in other contexts too. It can also mean burnout in more abstract contexts, but here it clearly means physical wear on the garment.

The subject is we.

נבדוק is the 1st person plural future form: we will check.

Hebrew often leaves out subject pronouns when the verb already shows who the subject is. So there is no need to say אנחנו נבדוק, unless you want emphasis.

In this kind of sentence, we can mean:

• the speakers literally
• the people carrying out a procedure
• an impersonal instructional we

Because in this sentence אם introduces an indirect yes/no question.

After verbs like:

• לבדוק = to check
• לדעת = to know
• לשאול = to ask
• לראות = to see

Hebrew often uses אם in the sense of whether.

So:

• נבדוק אם הבגד לביש = we will check whether the garment is wearable

This is different from a conditional if like:

• אם ירד גשם, נישאר בבית = if it rains, we’ll stay home

Same Hebrew word, different function.

Because Hebrew usually does not use a present-tense form of to be in sentences like this.

So:

• הבגד לביש literally looks like the garment wearable
• but it means the garment is wearable

This is completely normal Hebrew.

Compare:

• הילד עייף = the child is tired
• החולצה נקייה = the shirt is clean
• הבגד לביש = the garment is wearable

In the past or future, Hebrew does use forms of היה:

• הבגד היה לביש = the garment was wearable
• הבגד יהיה לביש = the garment will be wearable

Because לביש is being used as a predicate adjective, not as an adjective directly attached to the noun.

In other words:

• הבגד לביש = the garment is wearable
• this is a full clause, so the adjective does not take ה־

Compare:

• הבגד חדש = the garment is new
• הבגד החדש = the new garment

That same distinction applies here. In the sentence you gave, לביש is part of the predicate, so no ה־ appears on it.

It is a real and correct Hebrew word, and it is easy to understand, but it can sound a bit formal, technical, or evaluative in this kind of context.

It means wearable, fit to be worn, or still suitable for wearing.

In everyday speech, some speakers might say something more explicit, such as:

• אפשר ללבוש את הבגד = you can wear the garment
• הבגד עדיין טוב = the garment is still fine
• הבגד עדיין ראוי ללבישה = the garment is still fit for wearing

So לביש is perfectly good Hebrew, but it has a slightly inspection/report-style feel here, which fits the sentence well.
