This chapter outlines directions for future research inspired by Mora Loss and Restoration (MLR) Theory. It first reiterates that vowel reduction involves mora loss, followed by optional processes such as feature loss and mora restoration. This approach unifies cross-linguistic patterns observed in languages such as New Zealand English and European Portuguese. While MLR Theory explains how vowels transition to non-moraic glides or schwas, it also calls for further empirical testing through detailed phonetic and phonological analysis. The chapter then extends the framework to consonants, syllables, and metrical feet. Mora loss may explain degemination in unstressed geminates, contextual weight alternations in codas, and the behavior of syllabic consonants. These predictions invite more data-driven research on how moraicity shapes both vowel and consonant reduction. Finally, the theory opens new avenues for reconsidering traditional metrical structures, particularly how non-moraic syllables challenge established assumptions about foot formation and prosodic hierarchy.
