Questions & Answers about píngmù shàng de gēcí hěn qīngchu.
The sentence breaks down like this:
屏幕上 = on the screen
的 = links a modifier to a noun
歌词 = lyrics
很 = very / a common adverb before adjectives
清楚 = clear
So the structure is:
[屏幕上的] [歌词] [很清楚]
= [the on-screen] [lyrics] [are clear]
A very literal gloss would be:
screen-on + de + lyrics + very + clear
In Mandarin, words like 上, 下, 里, 外 often come after a noun to show location. These are sometimes called localizers.
So:
- 屏幕上 = on the screen
- 桌子上 = on the table
- 墙上 = on the wall
This is normal Chinese word order. English says on the screen, but Chinese says screen + on.
Because here 屏幕上 is being used as part of a modifier before the noun 歌词.
- 屏幕上的歌词 = the lyrics on the screen
In this kind of noun-modifying phrase, 在 is often omitted.
You can sometimes say 在屏幕上的歌词, but it sounds heavier and is less natural in a simple sentence like this. The shorter 屏幕上的歌词 is the most common way to say it.
