Three-syllable transliteration mapping to English/German surnames in 'Go-bler' or 'Gob-ler' shape (Gobler, Cobbler, Goebler).
哥 covers 'Go-',
布 ('cloth') is a stable phonetic for the 'b' onset, and
勒 covers '-ler'. The 'goblin' rendering
哥布林 (with
林 'forest') is more common in fantasy translations;
哥布勒 with
勒 reads more like a personal name.
