What is the meaning of 'construct' in programming languages
does the word 'construct' have an relation to an object 'constructor' in other languages?
The sentence uses the noun, not a verb, meaning of the word "construct":
construct (n) - something (such as an idea or a theory) that is formed in people's minds.
In this case, "construct" refers to an abstract way of describing something (namely, a loop) in terms of the syntax of that particular language. "Language construct" means "a way to do [something] with that language".
In this case you can replace the word construct with syntax.

No. These two terms are different. There is nothing like constructor in C
It's a generic term that normally refers to some particular syntax included in the language to perform some task (like a loop with the condition at the end). It has no relation at all with constructors.1
- Well, besides the fact that constructors are a particular language construct in many OO languages.
