How to spell the word: ceiling correctly? How to check?
The word Ceiling turns out to be a masculine noun and second declension in which we select the zero ending: Ceiling-Ceiling-Ceiling.
The stress in it falls on the third syllable: the ceiling.
The root of the word turns out to be the morpheme CEILING: Ceiling.
Note that in this root there are two unstressed vowels O at once, and the word itself can be mistakenly written as patAlok.
We cannot check these dubious vowels in any way, and therefore their spelling in this dictionary word should be remembered. Although the first O is in the historical prefix PO: Ceiling-Ceiling.
The paired consonant K, which stands at the end of a word, can be checked with the plural of the noun ceilings.
I don’t know, maybe I’m wrong, but at school we were taught that the word ceiling is a dictionary word and such words must be memorized. So that is why it is also a dictionary word, because it is impossible to find a test word for it.
