Many English learners stop for a second when they see the words lynchpin and linchpin. They look almost the same.
They sound the same when spoken. Spell-check tools often do not help. Even native speakers argue about which one is correct.
This confusion happens for a few simple reasons. First, English has many words that sound the same but have different spellings.
Second, one of these words comes from old history, not modern daily life. Third, movies, news articles, blogs, and even teachers sometimes use different spellings.
Still, this word pair is very important. You will see it in work emails, news reports, business talks, school essays, and daily conversations.

By the end of this lesson, you will clearly know:
