Frequently asked questions
Is it in depth or in-depth?
Hyphenate it before a noun (an in-depth analysis) and leave it open after the verb (we analysed it in depth). This is the standard rule for compound modifiers.
What is the difference between in depth and in detail?
They overlap heavily. In detail stresses that many particulars are included; in depth stresses that the treatment goes beneath the surface to causes and implications, so a short piece can still be in depth.
Can something be too in depth?
Yes, and that is a normal criticism in writing and presentations: coverage that goes deeper than the audience needs. In that case, a summary with the detail in an appendix usually works better.
What is the meaning of in depth?
"in depth" (adverb) means thoroughly and in detail, covering all the important aspects of something.
