action
1
failure to include or do
The act of not including or not doing something that you should include or do.
用法パターン：
the omission of [something] (from [something])
よくある間違い：
Learners sometimes confuse "omission" with the verb "omit" and say *"the omit of his name"* instead of "the omission of his name". Also, "omission" is often misspelled or misheard as "emission" (which means something that is sent out, like gas or light) or "admission" (which is about allowing entry or acknowledging something). Pay attention to the prefix "o-" and the meaning of leaving something out.

oversight (Suggests an accidental omission, often through carelessness rather than intention.)

対義語
inclusion (Focuses on the opposite act of adding something rather than leaving it out.)
|

a thing that was left out
Something that is missing because it was not included, but it should be there.
用法パターン：
an omission from [a list/report/book]
よくある間違い：
Learners sometimes mix this sense with the more general action sense and use verbs that fit the action but not the thing. For example, saying *"we made an omission"* is possible but often unclear; in many cases it is clearer to say "there is an omission" when you mean a specific missing item.
類義語
gap (Emphasizes the empty space or missing part created by the omission.)
|
exclusion (Suggests that something was left out, often deliberately or as a policy.)
対義語
addition (Highlights something extra that is put in, the opposite of something missing.)
|
entry (In the context of lists or records, an entry is an item that is present rather than omitted.)

failure to act when required
Not doing something that you are expected or required to do, especially in law or in moral questions.
用法パターン：
an omission to [do something]
よくある間違い：
Learners may think "omission" only means forgetting something. In legal and moral contexts it can also mean a serious or punishable failure to act, even if it is not accidental. Also, "omission" here often appears with set phrases like "sin of omission" or "error of omission" rather than with everyday verbs.
類義語
default (In legal or formal contexts, means failing to do what is required, such as paying or appearing.)
|
dereliction (A very formal word highlighting serious or blameworthy failure to perform a duty.)
対義語
action (General opposite: actually doing something instead of failing to do it.)
