PREG is a colloquial term often used on online forums and social media. It is a shorthand for the word "pregnant". The spelling of the word is based on its pronunciation, which is /ˈprɛɡ/. The IPA phonetic transcription shows that the first syllable is pronounced with an open-mid vowel sound followed by a voiced alveolar plosive consonant, while the second syllable is pronounced with a high front vowel followed by a voiceless alveolar plosive consonant. Despite not being a traditional spelling of the word, its usage has become widespread in informal contexts.
