Collocations
Pro Tip
Prepositions Matter
Use 'in' for states (maintain in good health) and 'at' for levels (maintain at 100%). Avoid 'for' unless referring to financial support (maintain for your family).
Gold Rule
Active vs. Passive
Use active voice for clarity: 'She maintains her garden' (not 'Her garden is maintained by her' unless emphasizing the action itself).
Word Origin
From Middle English 'mainteinen' (to support, sustain), from Old French 'maintenir' (to hold in hand), from Latin 'manu tenere' (to hold in the hand). The prefix 'main-' comes from Latin 'manus' (hand), and 'tenir' from Latin 'tenere' (to hold).
Usage Notes
Commonly used with 'in' (maintain in good condition) or 'at' (maintain at a high level). Often confused with 'sustain'—'maintain' implies ongoing effort, while 'sustain' can imply endurance over time.
