傾= to lean; to tilt
頃 is the phonetic component in this character, the meaning it contains is irreverent to the character, we can ignore it.
The radical 人 is the semantic part of the character -- "Man leans"
The meaning of 'to lean/ to tilt' in 傾 extended to everything else besides humans. For example, you can say a tower is 傾斜的 (tilted) even a tower is not human
The 'lean/ tilt' meaning extended to many other meanings, for example, to 'pour out' (when pouring wind, you need to tilt the bottle); 'overflow' (liquid pouring out from a container when it is too full and it is an overflow).
