Etymology
the word 'calving' originates from the old english verb 'cealfian', meaning 'to give birth to a calf'. this verb is derived from the old english noun 'cealf', meaning 'calf'. the term's semantic extension to glaciology, referring to the breaking off of ice, is a metaphorical application from the late 19th century, drawing an analogy between the detachment of a large ice mass and a cow giving birth. this metaphorical use elegantly captures the sense of a larger entity releasing a distinct, smaller offspring. the core root can be traced back to proto-germanic kalbaz and ultimately to the proto-indo-European gelbʰ-, which carried meanings related to womb and young animal.
Analysis
the word is a simplex form derived from the verb 'calve'. it is not productively segmented into smaller, independent morphemes in modern english.
