Pay attention to where the stress is placed in Italian: leggere (means light, not heavy) while leggere means "to read" and is a verb. Since the accent sign is used only when it falls on the last syllable of two- or more syllable words (as realtà, vedrò, finì) only the meaning will distinguish these words written in the same way but with different stress and meaning. Another common example is ancora (=a noun, anchor) and ancora (an adverb= again, still).
"Piatto ricco, mi ci ficco" means "the dish is rich, so I'll dive in" and is usually used in card games when the the stakes are high, and a player is more willing to get in.
