English contains many uncommon words that are only used in specific contexts. In some cases, these words may cross the border into jargon, but in other cases, they allow for clear distinctions between concepts which may be difficult to explain using other words. Endorsement and indorsement are two similar words that many writers confuse. Indorsement is the rarer term, and it only appears in reference to certain financial documents. Still, if you are writing in the financial industry or reading legal documents, you will need to know the difference between these words, as well as when to use each.
Endorsement as noun:
Indorsement as noun:
“This indorsement is illegible,” said the banker, in exasperation.
Endorsement or indorsement
While indorsement and endorsement are both nouns, they refer to different concepts. An endorsement is a public indication of approval or support. An indorsement is a legal signature on some financial documents, like checks. Indorsement is used in American English, but only rarely. If you are not writing for an audience which expects strict legal terminology, you can use endorsement in these contexts as well. A helpful way through which you can remember the them is that since endorsement and everyday both begin with the same letter, you can remember to use endorsement in most day-to-day writing contexts.
