What does 'put shelves up' mean?

Question

What does 'put shelves up' mean in the sentence: 'I've been meaning to put shelves up in the lounge for years but I haven't had time.' Does put shelves up mean the same as 'install'? Or does it specifically mean 'to install the shelves at a high place in the lounge'? Does 'up' in 'put up' indicate the level / place to where something (the shelf) is going to be installed in the lounge?

Answer 1

Your first thought is correct! "Put up" generally means "to install," regardless of the level.
