The 者 (Person / -er) & 耂 (Elder) Kanji Family: 者 (Someone), 医者 (Doctor), 考 (Think) & 古 (Old)

Look at the top of 者 (Someone / -er suffix) and 考 (Think): both wear 耂 (土 Earth + a long diagonal cane slash)! Whenever 者 attaches to a compound like 医者 (doctor), it means 'the person who does X'!

In English, we add -er or -ist to create professions (teach → teacher, medicine → doctor). In Japanese, that exact suffix is 者 (sha / mono): combine 医 (Medicine) + 者 (Person) = 医者 (isha — Doctor)!
