Pro Tip
Adjustable vs. Flexible
'Adjustable' usually implies a mechanism or setting designed to change (like an adjustable belt or chair height), whereas 'flexible' often refers to a physical property of bending without breaking or a person's adaptable personality.
Gold Rule
Keep the root intact
When adding '-able' to 'adjust', do not change any letters in the root word: adjust + able = adjustable.
Word Origin
Formed from the verb 'adjust' (from French 'ajuster', meaning to arrange or fit) combined with the English suffix '-able' (capable of being).
Usage Notes
Use 'adjustable' when a specific mechanical feature or setting allows alteration. Compare with 'flexible', which describes material elasticity or general adaptability rather than built-in settings.
