'annaline' originates from the given name 'Anna' (ultimately from Hebrew 'Hannah', meaning 'favor' or 'grace'), combined with the suffix 'line' (a diminutive/ornamental suffix found in Germanic and French name-formation).

'annaline' developed as a compound/variant of 'Anna' + '-line' (compare names like 'Anneliese' and 'Annalise') in modern European naming practices and was adopted into English usage as a feminine personal name.

Initially linked to the meaning of 'Anna' ('grace' or 'favor'), the form 'annaline' has come to function primarily as an identifying personal name without a separate literal meaning.
