实 is a bound morpheme that rarely appears alone and mainly serves as a component in compound words. Its core meanings revolve around 'real, true, actual, solid' — e.g. 实在 (really/honest), 实际 (actual/practical), and 实验 (experiment). While the dictionary lists 'fruit' and 'seed', these senses only appear in compounds like 果实 (fruit) or rely on context; 实 by itself does not mean 'fruit' or 'seed'.
