Assuming "fiance" refers to "fiancé" and not "fiancée", you can construct your proposal by choosing one option in each set of parentheses:

(Fen/Laan) hi (meyz/kos) (dii ahmul/ahmuli)?

"(Will/Want) you (become/be) (my husband/my husband)?"

Note that fen losei is unattested and possibly ungrammatical as losei is already a contraction of los hi 'are you'.

Celtic patterns have always been associated with eternity, protection, and love, making them a great choice for an important moment like a proposal. Plus, the website offers a wide range of patterns to suit different preferences.
