齁 is colloquial and dialectal. Besides 'to snore', northern speakers use it for food too salty or sweet to swallow (齁咸), and as an intensifier like 'super' (齁甜 = super sweet).
The 鼻 (nose) radical on the left carries the meaning: snoring is a noise made through the nose. It is one of the rarer radicals, also seen in 鼾 (to snore loudly).
Right side 句 is the sound element, here read in its old gōu value, drifting to hōu. It contributes no 'sentence' meaning — it is purely the phonetic tag for this snoring word.
