The influence of IE laryngeal segments and their physical presence in early Germanic have frequently been adduced to explain some five classes of problematic phenomena of the early Gmc. languages. These problems are: first, that of the past forms of the seventh-class strong verbs; second, the so-called Verscharfung; third, the Gmc. e r -vowel; fourth, the e-to-/ change; and finally, various Gmc. etymologies. The laryngeal explanations of these five phenomena are deficient and alternative explanations are preferable. Therefore, there exists no hard evidence for the presence of laryngeal segments in later pre-Gmc. Indo-European nor in early Germanic.
