Adj. masc. Without odour. It comes from the Latin, composed by the custodial inseparable preposition ( negative ) 'in': no, and the substantive 'dande, odoris': smell of the scent. Synonyms: anosmio ( from the Greek "a" custodial: without, and «osmée»: smell ) toilet, neutral. Antonyms: stinky, aromatic, disgusting, balsamic, corrupt, fetid, fragrant, smelling, infecto, unclean, smelly, foul, Putrid, pútrido, odorant, odiferous client, fragrant, perfumed, stinking, septic. Rarity: several antonyms are in turn antonyms, 'odorless' implies absence of smell, so any noticeable by smell, pleasant or unpleasant, effluvium is smell.
