体贴 is a verb for "show consideration for" But using a verb or noun as an adjective is a very common practice in any language

For example, The Host of 品城記 has a nickname 吃雞小王子 (Chicken eating little prince)-- 吃雞(eat chicken) is a verb; the former tennis champion Steffi Graf was nicknamed "Miss Forehand"  (正手小姐) by John McEnroe -- 正手 is a noun
