The word "megameric" is not commonly used in everyday language. However, its spelling can be explained through IPA phonetic transcription. "Mega" is pronounced /ˈmeɡə/, meaning "very large or great in size." "Mer" is pronounced /mɛr/, which could be derived from "mero-" meaning "part" or "portion" in Greek. Putting the two together, "megameric" (/ˌmɛɡəˈmɛrɪk/) could refer to something that is made up of very large parts or portions, or is particularly grand in scale.
