3. A syllable containing a short vowel followed by two consonants ([§ 5], B, 2) is long, even when one of the consonants is in the following word; as, terret populum. Occasionally the syllable is long when both consonants are in the following word; as, prō segete spīcās.
4. Compounds of jaciō, though written inicit, adicit, etc., have the first syllable long, as though written inj-, adj-.
5. Before j, ă and ĕ made a long syllable, e.g. in major, pejor, ejus, ejusdem, Pompejus, rejēcit, etc. These were pronounced, mai-jor, pei-jor, ei-jus, Pompei-jus, rei-jēcit, etc. So also sometimes before i, e.g. Pompe-ī, pronounced Pompei-ī; re-iciō, pronounced rei-iciō.
