比较 (bǐjiào) has two main uses: as a verb meaning 'to compare' (similar to 相比 but more versatile), and as an adverb meaning 'relatively, quite, rather' (the everyday word for this sense, less formal than 较 and less strong than 相当). As a verb, it can take an object directly (比较价格) or appear in 和/跟...比较; as an adverb, it goes before adjectives (比较冷).
