recite, chant
誦 centers on vocal delivery of text from memory or in a rhythmic way: reciting aloud or chanting. The two given meanings are closely linked as spoken performance of words.
誦 combines 言 (speech, words) with 甬, which likely contributes the sound and may relate to a pathway or channel, suggesting words flowing in a recited pattern.
Words 言 flow through a channel 甬 like a chant or recitation. Picture a stream of spoken words passing smoothly along a path.
For ショウ, imagine a show where performers recite ancient poems on stage: show -> ショウ, and the words flow like a chant.
