그냥 (geunyang) = just (but I'm not sure if it's the word that you're asking about)
좀 (joem) = just (as in "a little/some") 좀좀 is stronger (means a little)
(about "amureochi" I have no idea, sorry, please use Hangul for writing in Korean, romanisation can be very confusing and it's actually harder to read correctly than learning Hangul)
아직 (ajik) = yet/still
어리 = young 어려서 (eoryeoseo) = 어리 + "어서" ending meaning "so..."
so 아직 어려서 = still young so...
그래서 (geuraseo) = "so" - it has a meaning like "it's this way, so..."
