The word comes from ancient Chinese tallies (符): bamboo or wooden tokens split in two, where both halves had to match (合) perfectly for verification. This is the origin of 'conforming' or 'matching'.
grammar
符合 takes an object directly: 符合要求 (meet requirements), 符合标准 (meet standards), 符合条件 (meet conditions). No 了 needed for stating facts.
