An invisible thing can't be seen, but what do you call something which cannot be smelled?

    For all five: invisible, silent, tasteless, odorless, intangible. Sep 5, 2015 at 11:12

    @PeterShor Or if you want to stick to more parallel words (negated with in-): invisible, inaudible, ingustable, inodorous, intangible. Can't find a proper -ble parallel for smell, unfortunately. Sep 5, 2015 at 11:46

    @JanusBahsJacquet Someone later suggested 'inolfactible' for my question, so that would match your set. Oct 6, 2015 at 7:33

Inolfactible. Olfactible is in the O.E.D.

  • This is very rare.

  • @Mitch Rare yes, but I feel it matches more with "visible" than the other suggestions. It's both specific to the sense of smell and connotates more of the absence of sense itself than just the object's inert quality. Sep 7, 2015 at 9:55


An odour is a smell.


You'd need some context to make this work, but I rather like


(meaning that something can't be perceived by the senses or a sensor)


Tea? Soap?

unscented, means it hasn't had any scent added.

Shirts? Socks?

clean, means they're recently washed.

Pebbles? Chemicals?

inert, means it's unreactive and won't stimulate those nerve-endings.

inert (Merriam-Webster)

3 : deficient in active properties; especially : lacking a usual or anticipated chemical or biological action

Forensic specimen?

odourless, (odorless) free of odour

    You can still generally smell unscented tea and soap, as well as pebbles and clean socks, though. They're not odourless as such. Sep 5, 2015 at 11:59
  • @JanusBahsJacquet, well, it's comparative. People will continue to be congratulated that their socks don't smell. Others will continue to lament that a new rose has no smell. Ultimately it was music that Auden claimed was "invisible...and does not smell." Any others?
