A very rare term meaning sounding like waves or producing a sound like the motion of waves.
From Latin 'fluctus' (wave) combined with '-sonant' meaning sounding (as in 'consonant'). This is an invented scholarly term for describing wave-like sounds, found only in specialized or historical texts.
Fluctisonant is what a poet would call the sound of the ocean—it literally means 'wave-sounding,' combining two Latin roots into one magnificent word that probably nobody has actually used in conversation.
