While it lacks a standardized spelling, "tuh" is often written as "tuh" or "tuuh" and pronounced as /tʌ/ or /tʊ/. It is commonly used as an interjection or vocal sound to convey a range of emotions or attitudes, particularly to express disbelief, dismissal, nonchalance, or a lack of interest.
When used as an interjection to convey disbelief, tuh often carries a sense of disagreement or incredulity towards a statement or situation. It implies that the speaker finds something absurd, unbelievable, or unworthy of consideration. For example, if someone says, "I won the lottery!" and another person responds, "Tuh, as if!", they are expressing skepticism or doubt about the claim.
Tuh can also be used to dismiss or downplay somebody's argument or opinion. It has a connotation of disagreeing or rejecting someone's point of view, often in a dismissive or nonchalant manner. For instance, if someone argues that a movie is amazing, and another person responds, "Tuh, it was boring," they are indicating their disagreement and lack of enthusiasm about the movie.
In summary, "tuh" is an expressive interjection used in AAVE to convey disbelief, dismissal, indifference, or disagreement. Its precise meaning and connotations may vary depending on the context and speaker, but it typically serves to express skepticism, disregard, or a lack of interest in the topic at hand.
