Meaning: The root "sign" means "a mark".
Pronunciation: As a root, the vowel "i" is pronounced like the "i" in "sit" and the "g"
is pronounced as in "big". (This is NOT like the word "sign" which rhymes with "wine"!)
Example 1: A "signature" is what you write when you sign your name, for example,
at the end of a contract. "He signed the contract and they started their business partnership
immediately".
Example 2: A "signal" is any kind of mark or noise to show something will
start or stop. (1) "The traffic signal turned red, so all the cars stopped". (2) The official made
a hand signal and the players got ready for a corner kick".
Example 3: To "resign" means to tell your boss that you quit, often by giving
your boss a "resignation letter".
