「珍」 mostly appears inside compounds meaning rare and curious, sometimes with a comic tinge — 「珍品」「珍事」「珍回答」 — and is seldom used on its own. For everyday 'rare' say 「珍しい」; for something odd say 「変」 or 「奇妙」; for unconventional character or ways, 「風変わり」. Written prose offers 「まれ」 for infrequency and 「稀覯」 for rare books; 「非凡」「並み外れ」 praise the exceptional, while 「異常」「異様」 flag the abnormal or unsettling. The opposites are 「普通」 and 「平凡」.
