The word "hadst get together" is not a correct spelling. Perhaps the intended phrase was "had get together," which is spelled with the IPA phonetic transcription /hæd ɡɛt təˈɡɛðər/. The word "had" is pronounced with the vowel sound /æ/ as in the word "cat." The phrase "get together" is pronounced with stress on the first syllable of "together" and the vowel sound /ə/ as in the word "a." The correct spelling and pronunciation can help clarify the intended message.
