Irrespective of cost, we will have the work done.
Regardless of cost, we will have the work done.
1. irrespective 跟regardless在這種句式中是什麼詞性(形容詞片語...副詞片詞)? 在字典中的解釋只有它們能作為副詞跟形容詞使用 所以我分不太清楚
2. 又如full of stock/out of stock...out of 跟 full of是形容詞片語還是介詞片語?
3. 片語中有那類能跟Irrespective/Regardless of一樣的用法? 就像because of cost, we will have the work done 這看起來就很通順 但Out of cost, we will have the work done卻又怪怪的?
