The dirty window

[bagzi94]

Open up the dirty window
Let the sun illuminate the words that you could not find

Is this an idiom or strict sense?

Never heard/read the expression and I don't know the meaning.

So, this is not an idiom? The window is dirty
like house, garden, hands can be dirty?

Window, houses, gardens, hands and, in a different sense of the word, minds and old men can be dirty. This is natural English - noun + BE + adjective. We don't call this 'an idiom'.

In your post,

Open up the dirty window
Let the sun illuminate the words that you could not find

the words appear to be used metaphorically. Like billmcd, I don't know what they mean.

It's a song. Unwritten, by Natasha Bedingfield.

It is indeed being used metaphorically.

It's up to the listeners to detemine what this metaphor means to them.
