I'm aware of the difference between Prone vs. Supine vs. Prostrate, but I'm trying to find the opposite of the related word 'recline'.
Every web or dictionary search brings up 'upright' as the antonym for reclined. That's not what I mean.
Where I envisaged a reclining person on their back (supine), I'm trying to find the word for lying on one's front in the prone position.
A good example would be the stereotype of Romans eating on their stomach:
Or this person reading while resting on a pillow:
If I were to use it in a sentence, it might be:
Derrek's partner reclined on the sunlounger, in contrast Derrek <word>ed by the pool.
I don't want to use the word prone, as I'm not using the word supine; 'prone' would feel out of place.
