easy to see · adjective · B1
Easy to see or understand, so that no one needs it explained.
明顯的
核心畫面
Something standing right in your path, so you cannot miss it. The Latin root literally means 'in the way / meeting you head-on' — when a thing is obvious, it is so much in front of you that it needs no explanation; you just see it.

可以想成一個東西正好擋在你走的路上，你想不看到都難。它的拉丁字根字面意思就是「迎面而來、擋在路中央」——當一件事 obvious，它就近在眼前、明擺著，根本不必有人解釋，你一看就懂。其他用法都是同一個畫面的延伸：感受露得太明顯、大家早就看出來的那個選擇、明擺在眼前最該做的那一步。From the word’s history
From Latin 'obvius' = 'in the way, meeting head-on', from 'ob viam' (in the way / against the road). What lies right in your path is what you cannot help noticing.
來自拉丁文 obvius，意思是「擋在路上、迎面相遇」，由 ob viam（在路上、對著路）組成。正好橫在你路上的東西，就是你想避也避不開、一定會注意到的東西。

Three branches
明擺著該選 / 該做的那個
從「一看就懂」延伸到選擇與行動：答案明擺在那裡，所以那個人選、那一步，是大家眼前自然會指向的。
expected/natural choice · adjective · B1

Used in 'state the obvious', meaning to say something everyone already knows.
明顯的事（多此一舉）

Easily discovered, seen, or understood; self-explanatory.
- Carried somehow, somewhither, for some reason, on these surging floods, were these travelers, of errand not wholly obvious to their fellows, yet of such sort as to call into query alike the nature of their errand and their own relations.
