Can you give an example? Google is drawing a blank for that. My favorite piece of Japanese syntax is that adjectives can be conjugated for tense and conditionals, meaning that "It was delicious" has to be expressed as "It is delicioused" (oishikatta desu) and you can say "if it had not been red" with a single word (akakunakattara).
