     Finally, it should be noted that laryngeals not adjacent to syllabics were apparently deleted by three different rules.

The term laryngeal in Indo-European studies is but an anachronistic misnomer, retained only because it has been established as a standard term for those three phonemes. The exact phonetic value of Proto-Indo-European laryngeals is unknown, but it's generally agreed that not all of them were real laryngeals.
