What is the opposite of valuable or something of value

[oscarina]

What word describes something of no value, is it invaluable?

[NazNomad]

Worthless

[boxtops]

I agree with Naz - invaluable actually means the same as valuable, something you can't do without.

[Buenchico]

Valueless?
Worthless?

('Invaluable' means 'having incalculable monetary worth')

[factor-fiction]

A bit like 'flammable' and 'inflammable'

Chris is right, it's one of those funny words where the negative form does not mean what you might expect. The classic to my mind is 'flammable' and 'inflammable' which have exactly the same meaning (although the prefix 'in' in this case is not a negative).

No invaluable means the almost the same as valuable.....stupid language English isn't it> You need worthless. I would suggest.

Thanks dr b! So student wasn't wrong in using the word disvalued!

Whoa! Very interesting discussion about negative prefixes and their relative force, but we don't want to give the pedants a field day. Unvaluable is in the dictionary, disvaluable is not. Compare 'unsatisfied' and 'dissatisfied'. Both correct words, but with a subtle difference in meaning. A bit too late for me to get on my high horse over this,but food for thought, nevertheless.

Correction. Disvalued IS in the dictionary,but does not mean the same as unvalued as previous posters have kindly pointed out. 'Dis' tends to suggest 'opposite' rather than just 'not'
