good
👍 挺 = quite/rather + 好 = good; literally 'quite good'
挺 on its own means to stick out or hold up straight, and as an adverb it softens to 'quite' or 'rather'. Pair it with 好 (good) and you get a casual, very common way to say 'pretty good' or 'very good'.
挺 — hand radical 扌 + 廷 (court)
A semantic-phonetic compound: 扌 (hand) gives the meaning, while 廷 supplies the sound. The original sense was to pull out or extend with the hand, which broadened to 'straight,' 'erect,' and 'to stand upright.' Modern uses like 'quite' or 'rather' come from this idea of standing out prominently.
好 — woman 女 + child 子
好 is an associative compound showing a woman 女 beside a child 子, depicting a mother with her baby. From this image of maternal affection it came to mean 'good, fine, pleasing.' The reading hǎo means 'good'; read hào it means 'to like.'
