inclined
Leaning or likely to do or prefer something.
Inclined means leaning toward something, either physically or in terms of preference or tendency.
When something is physically inclined, it slopes or tilts at an angle. An inclined plane is a flat surface that slants upward, like a ramp leading into a building or the sloped bed of a dump truck. Ancient Egyptians used inclined planes to move massive stone blocks up the sides of pyramids. Even a playground slide is an inclined plane, just one designed for fun rather than construction work.
When a person is inclined toward something, they naturally tend in that direction or feel drawn to it. If you're inclined to believe your friend's explanation, you lean toward thinking they're telling the truth. Someone musically inclined has a natural interest or talent in music. You might say “I'm not inclined to go to the party” when you'd rather stay home and read.
The phrase “if you're so inclined” means “if you feel like it” or “if that interests you.” A teacher might say, “You can write an extra report if you're so inclined,” meaning it's optional for students who want the challenge. The word suggests a gentle pull or preference rather than a firm requirement or a strong force.
