Flat cutting part of tool or weapon
The flat, thin, sharp part of a tool or weapon that cuts things.
الگوی کاربرد:
the blade of [a tool/weapon]

هممعنیها
cutting edge (Describes the sharpened edge itself rather than the whole flat cutting part.)

Knife used as a weapon
A knife or other sharp weapon that a person carries, often for fighting.
الگوی کاربرد:

اشتباه رایج:
Learners may confuse this with the normal, non-weapon sense of "blade" (the cutting part of a tool). In crime or street contexts, "a blade" often means the whole knife as a weapon.
هممعنیها
knife (The general word for this object; "blade" in this sense is more informal and often suggests an illegal weapon.)
متضادها
firearm (A weapon that fires bullets, often contrasted with knives or other blade-type weapons.)

The flat part of a machine, like a fan or propeller, that turns and pushes air, water, or something else.
الگوی کاربرد:

اشتباه رایج:
Learners sometimes think this only means something that cuts. In machines like fans or turbines, the blade’s main job is to move air or water, not to cut.
هممعنیها
rotor blade (A more specific term for a blade on a rotating part such as a helicopter rotor or turbine.)
متضادها
hub (The central part of a rotating machine that the blades are attached to, opposite in position to the blade.)

One thin, narrow leaf of grass or a similar plant.
الگوی کاربرد:

هممعنیها
leaf (General word; a blade of grass is a special long, narrow type of leaf.)
متضادها
lawn (Refers to the whole area of many blades of grass together, the opposite of a single blade.)
