Resembling or characteristic of a gulf in appearance or form; having the qualities of a large indented bay.
Compound of 'gulf' (from Old French 'golfe', from Greek 'kolpos') plus '-like' (Old English 'gelic', meaning similar). The '-like' suffix is productive in English and can be added to many nouns to mean 'resembling' or 'of the nature of'.
The '-like' suffix is one of English's most creative features—you can add it to almost any noun to create new descriptive words! 'Gulflike' is just one of millions of potential compounds, which is why English never runs out of new ways to describe things.
