Partially, partly, or in a halting manner; somewhat reluctant or hesitant (Scottish).
From Scottish haffle (to hesitate) plus the diminutive or adverbial suffix -ins, creating an adverb meaning in a hesitant or partial manner.
Scottish adds suffixes like -ins to turn adjectives and verbs into adverbs in ways English doesn't—it's like their grammar has more building blocks to work with.
