TLDR
UStee-el-dee-AHR/ˌti ɛl di ˈɑɹ/UKtee-el-dee-AH/ˌtiː ɛl diː ˈɑː/
- 1Initialism of "too long; didn't read": said of a text too long to bother with, or used to introduce a brief summary of it.
The report was dense, so an editor added a TLDR summarizing the key findings.
Most readers skip straight to the TLDR before deciding whether to read on.
Note
The spelling drops the semicolon of tl;dr and capitalizes every letter, which makes it quick to type and easy to spot as a heading. It comes from Internet writing and now works as an ordinary countable noun for a short summary: an editor adds a TLDR to a dense report, and readers skip straight to the TLDR. It belongs to informal prose, so leave it out of formal writing.
