Do you suffer from molassitude?

"Lassitude" by Henri de Toulouse-Lautrec

Dr. Goodword enlightens us on similar words for a familiar state of being. Taken together, he writes, these words provide a nice little lexical toolkit for dividing inactivity into several more precise senses.

lassitude (læs-ê-tyud) means:

1. Lethargy, torpor, listlessness, a lack of energy, spirit, vitality.
2. Apathy, a lack of interest in things.

Lethargy is a drowsiness that interferes with alertness.
Torpor is a deeper drowsiness, right on the edge of sleep or unconsciousness.
Listlessness suggests more of a disinclination to move or be active rather than a change of mental state.
Lassitude is more of a lack of motivation to act.
Molassitude would be the slowest sort of lassitude—if only it were a word!

Lassitude, the good doctor informs, comes from Old French which inherited it from Latin lassitudo, the noun from adjective lassus "weary". This word is based on a stem (las-) that goes back to Proto-Indo-European *le- "let go, slacken" plus a suffix -d, *led-, that also gave English let and late, not to mention German lassen "let". With the suffix -n, it pops up in Russian as len' "laziness", in Latvian as lens "slow", and Latin lenis "soft, gentle", which is also at the bottom of English lenient.
