よくある間違い：
Learners sometimes confuse the spelling and pronunciation of "gem" with "gym"; they are unrelated words. Another mistake is using "gem" to mean any piece of jewelry (e.g., "I bought a gem" when they mean "bracelet"); strictly, a gem is the stone itself, not the whole piece of jewelry.
意味

|sparkling gem

類義語
