Questions & Answers about חומרי הגמר הגיעו היום.
Because חומרי is the construct form of חומרים.
- חומרים = materials
- חומרי = materials of ...
Hebrew often links two nouns this way. This structure is called the construct state or סמיכות. So:
- חומרי הגמר = finishing materials / the materials of the finish
In a construct phrase, the first noun normally does not take ה־. The definiteness is usually shown on the second noun.
So:
- חומרי הגמר = the finishing materials
- חומרי גמר = finishing materials, more indefinite or general
Even though חומרי has no ה־, the whole phrase can still be definite because הגמר is definite.
