When you are talking about discussing something in great detail, do you want ‘indepth’ or ‘in depth’?
The word you want is ‘in depth.’ Just like the term ‘a lot,’ in depth is often mistaken to be one word—but don’t make that mistake!
If you want to use the term ‘in depth’ as an adjective describing a noun, hyphenate it.
- I would like to study that topic in depth (two words).
- We have begun an in-depth (hyphenated) study of the rock formations.
‘Indepth’ as one word is a non-standard spelling, so don’t use it.
