roca
/ˈroka/ · A2 · noun · f
rock
🪨 roca = rock: same r-o-c skeleton, just swap the k sound's spelling and add -a
Roca and English rock are cousins, both tracing back to Medieval Latin rocca. Keep the r-o-c, end in -a, and note it is feminine: la roca. A rocky place is rocoso, built on the same root.
