Questions & Answers about Bu yedi bebek aç.
Why is it bebek instead of bebekler if there are seven babies?
In Turkish, whenever you use a number before a noun to state how many there are, the noun stays in its singular form. You must say yedi bebek (literally "seven baby"), never yedi bebekler.
Why does the sentence use Bu (this) instead of Bunlar (these)?
In Turkish, pointing words like bu never take a plural ending when they are attached directly to a noun. You always use bu, whether it is bu bebek (this baby) or bu yedi bebek (these seven babies). You only use bunlar when it stands alone as a pronoun, like in the sentence "These are babies" (Bunlar bebek).
Where is the word for "are" in Bu yedi bebek aç?
There is no separate word for "are" here. In Turkish, when describing a subject in the third person (he, she, it, or they), the "is" or "are" is usually just implied. Placing the subject (Bu yedi bebek) and the adjective (aç) together is enough to mean they "are" hungry.
Does the adjective aç (hungry) need a plural ending since we are talking about multiple babies?
No, adjectives acting as the verb of the sentence don't usually take plural endings, and they definitely don't here because the number yedi makes the subject grammatically singular anyway. The base form aç is all you need.
