Complete answer: In grammar, a substitute is used as a noun to refer to a
word that serves as a particular kind of replacement. When one word replaces an entire

the phrase ‘the occurrence and development of events by chance in a happy or beneficial
way’ can be substituted by the word ‘serendipity’.
The only way to identify them correctly is to memorise them or use etymology to guess
them as accurately as possible.
