bough
Pronunciation: /baʊ/

Origin:
Old English bōg, bōh 'bough or shoulder', of Germanic origin; related to Dutch boeg 'shoulders or ship's bow', German Bug 'ship's bow' and 'horse's hock or shoulder', also to bow3

Do not confuse bough with bow. Bough means 'a branch of a tree' ( boughs laden with blossom), whereas bow means 'bend the head' ( he bowed to his father) or 'the front of a ship'.
