'unevenly-grown' originates from the combination of 'unevenly' and 'grown', where 'unevenly' is derived from 'uneven', meaning 'not level or smooth', and 'grown' is the past participle of 'grow', meaning 'to increase in size'.

'unevenly' changed from the Old English word 'unefen', meaning 'not even', and 'grown' from the Old English 'growan', meaning 'to grow'.

Initially, 'unevenly' meant 'not level', and 'grown' meant 'to increase in size'. Together, they describe something that has increased in size in an irregular manner.
