The spelling of "hadst hold up on" is a bit convoluted, but can be explained through the use of IPA phonetic transcription. "Hadst" is an archaic form of "had", pronounced /hædst/, with the "st" representing the suffix "-st" used for the second-person singular in Early Modern English. "Hold up" is pronounced /hoʊld ʌp/ and means to suspend or delay. "On" is pronounced /ɒn/ and denotes continuation or progression. Together, the phrase means to delay or postpone something that was previously planned or in progress.
There doesn't seem to be a widely recognized or standard dictionary definition for the term "hadst hold up on." However, we can extrapolate potential meanings based on the words used in isolation.
1. "Hadst" is an archaic second-person singular past tense of the verb "to have," used in Early Modern English. It is derived from Middle English and has no equivalent in contemporary English.
2. "Hold up" is a phrasal verb which generally means to support, sustain, or keep something in an elevated position. It can also refer to delaying or postponing an action.
3. "On" is a preposition indicating position or location.
Combining these words, "hadst hold up on" could potentially have the following interpretations:
a) It could represent an archaic or literary expression, meaning that you (the person being addressed) had previously supported or sustained something in an elevated position or location.
b) It could also imply a delay or postponement of an action or task that you were previously supporting or sustaining.
However, without proper context or a more established usage, it is difficult to determine the precise meaning of the phrase "hadst hold up on" beyond these educated interpretations.
