The spelling "dost something it" is incorrect in Standard English. However, it may be a non-standard or archaic usage of "dost" which is the second person singular present tense form of "do" in Early Modern English. The word "something" is spelled as it is pronounced, /ˈsʌmθɪŋ/, with the stress on the first syllable. "It" is spelled as /ɪt/, with a short vowel sound and an unvoiced consonant at the end. Overall, it seems to be an unusual combination of archaic and modern English.
There is no specific dictionary definition for the phrase "dost something it" as it is an incomplete and grammatically incorrect phrase. However, we can provide a general explanation for each word in the phrase to help understand their individual meanings.
1. Dost: Although its archaic form is rarely used today, "dost" is the second-person singular present tense of the verb "do" in Middle English. It is primarily associated with Shakespearean and Old English literature, meaning "you do" or "you perform."
2. Something: A pronoun used to refer to an unspecified or unknown thing(s). It indicates an object, event, or action that is not explicitly identified or particularized.
3. It: A pronoun widely used to represent a singular inanimate object or an animal of unknown or unspecified gender. "It" is also often used as a placeholder subject when there is no specific noun referred to.
Combining these individual meanings, "dost something it" could potentially be interpreted as an incomplete sentence in old English that suggests the second person singular (you) performing an unspecified action to an object or animal. However, the lack of proper grammatical structure makes it difficult to assign a precise definition without additional context.
