아침 식사를 준비하다.

The phrase '아침 식사를 준비하다' is composed of several elements. '아침' (achim) means 'morning'. Its etymology can be traced back to Old Korean, with similar forms found in other Altaic languages. '식사' (shiksa) means 'meal' or 'dining'. This Sino-Korean word derives from the Chinese characters '食' (shik, meaning 'food' or 'eat') and '事' (sa, meaning 'matter' or 'affair'). '를' (reul) is an object-marking particle, indicating that '식사' is the direct object of the verb. '준비하다' (junbihada) means 'to prepare' or 'to get ready'. This verb is also Sino-Korean, formed from '準備' (junbi, meaning 'preparation') and '하다' (hada, a light verb meaning 'to do'). '準備' itself comes from the Chinese characters '準' (jun, meaning 'accurate' or 'standard') and '備' (bi, meaning 'to provide' or 'to prepare'). Therefore, '아침 식사를 준비하다' literally translates to 'to do the preparation of the morning meal'.
