不管是谁对你们动的手: I've been quite lost towards that end "动的手". Could anyone explain that for me?
动手 is a compound word made up of 动 (move/ start) and 手 (hand). Together as a single word, it means 'take action', and the most common extended meaning is 'start to attack'
Since 动 and 手 in 动手 can be broken down to [v] +[n], you can add possess marker 的 before the noun 手 to reclaim the noun status of 手. And a subject (in this case, 谁) before the verb 动 would possess the noun
Example
动手 - start to attack
谁动手 - who started to attack (v)
谁动的手 - the attack(n) that started(v) by whoever(n)
手 has become a noun for 'attack' in this instance
Similar example:
[唱(v): sing + 歌(n): song] = [唱歌(v): to sing]
我唱歌 = 我(n) + 唱歌(v)
我唱的歌 = the song that I sing
歌 in 唱歌 reclaims its noun status and means 'song'
More examples:
開車(v): to drive --&gt; 他開的車 (車 is a noun here for 'car') - the car he drives
做飯(v): to cook --&gt; 姊姊做的飯 (飯 is a noun here for 'meal') - the meal my sister cooked
