amarrar

to tie; to moor

Borrowed from French amarrer (“to moor”), borrowed from Dutch aanmeren (“to tie or anchor the boat at the quay”). The Dutch aanmeren comes from aan- + meren (“to moor”), from Proto-Germanic *mairōną, from Proto-Germanic *mairją (“mooring post”), likely formed as Proto-Indo-European *(H)moi- (“to strengthen”) + *ro- similarly to Latin mūrus (“defensive wall”), see *mey-.
