That Semitic interpretation is plausible. I can't remember enough about Aramaic to comment, but the bits all look close to the appropriate Hebrew or Arabic bits.

a- Prefix 'I' used in imperfect and future forms.

bara The word 'created' in Genesis 1.1, not the usual Hebrew word for 'made'. (But this is perfective, so wouldn't take the a- prefix.)

ka 'like, as'

dabar 'word'

and finally a possessive suffix, though -ka is the Semitic for 'your' masculine singular.
