Several parts combine into one character.

果 is a pictograph showing a tree (木) with a round fruit hanging from its top — visible as the small enclosed ⊙ shape sitting on top of the tree. The oracle bone form is unmistakable: a tree with a round fruit clearly drawn at the apex. From this concrete arboreal image grew an extraordinary semantic spread: fruit → result / outcome / consequence (the fruit of an action) → "indeed / truly" (果然, "as expected, like a fruit ripening on schedule"). The pair 因 (cause) and 果 (effect / fruit) became foundational to East Asian causal reasoning, especially in Buddhist 因果 (cause-and-effect karma) doctrine.

Korean reading "gwa." 結果 (gyeolgwa, result — top-frequency word in formal Korean), 果樹 (gwasu, fruit tree), 成果 (seonggwa, achievement / outcome — used for measurable accomplishments), 因果 (ingwa, cause and effect), 果敢 (gwagam, bold / decisive — character extends to "decisive like a ripe fruit"), 果然 (gwayeon, "as expected / sure enough" — common discourse adverb in Korean writing).

Mandarin guǒ, 3rd tone. 果 (guǒ), 苹果 (píngguǒ, apple — top of every fruit-vocabulary list), 水果 (shuǐguǒ, fruit — the everyday word; literally "water-fruit"), 结果 (jiéguǒ, result), 后果 (hòuguǒ, consequence), 如果 (rúguǒ, "if" — one of the most essential conjunctions in spoken Mandarin: 如果你来 "if you come..."). The compound 如果 grammaticalized completely from "fruit" to a hypothetical particle.

Japanese on-reading カ (ka) — 結果 (kekka, result — note the doubled consonant from sandhi), 果実 (kajitsu, fruit — formal), 効果 (kōka, effect), 成果 (seika, achievement), 果樹園 (kajuen, orchard). Kun-readings: 果たす (hatasu, "to fulfill / complete / accomplish a duty" — used in formal contexts: 役目を果たす, "to fulfill one's role"), 果てる (hateru, "to end / die" — literary, often used for poetic deaths: 命が果てる, "life ends"). And 果物 (kudamono, "fruit" — the everyday Japanese word, with the irregular jukujikun reading where 果 + 物 reads as kudamono rather than the pronounceable phonetic kabutsu).

Memory aid: a tree (木) with round fruit (the round shape on top) — the visible fruit is the "result" of the tree's growth.
