The word "sacriplex" may seem like a difficult word to spell at first glance, but once broken down into its phonetic components, it becomes much more manageable. The first syllable, "sacri", is pronounced with the "sack-ree" sound. The second syllable, "plex", is pronounced with the "plekss" sound. Together, the word is pronounced as "sack-ree-plekss". The spelling of the word is based on the Latin roots of "sacrum" meaning sacred and "plexus" meaning interwoven, resulting in a term that evokes the concept of entwined holiness.
