Idiom Meanings

Idiom meanings are sometimes easy to understand and sometimes they are very difficult. An idiom is a group of words whose meaning is different from the individual words if you looked them up separately in the dictionary.

This list of English idioms begin with the letter D! You can find other idioms here at the main page of idiom meanings on this site.

Note: Each idiomatic expression does not always start with the letter “D.” This list is organized to  include English idioms whose main subject or action word starts with the letter “D.” (The main word is written below in all capital letters. For example, DEPTH: this is an in-depth list of idiom meanings starting with the letter "D.")
