Pronunciation: [bɪkˌʌm flˈat] (IPA) 
The spelling of the phrase "become flat" is relatively straightforward in English. The word "become" is pronounced /bɪˈkʌm/, with the stress on the "come" syllable. The word "flat" is pronounced /flæt/, with the stress on the only syllable. The "a" in "flat" is pronounced as the short "a" sound, as in "cat." Together, the phrase is pronounced /bɪˈkʌm flæt/.

"Become flat" is a phrase that refers to the transformation or alteration of an object or surface from a curved or irregular shape to a level or smoothed state. It is commonly used to describe the process or result of eliminating any kind of unevenness, bumps, or protrusions on a surface or object, rendering it smooth and level.
In a literal sense, the term can apply to various contexts. For instance, when considering a deflated or punctured inflatable object like a tire or balloon, "become flat" means the object loses its air or pressure, causing it to lose its original shape and become level or collapsed. Similarly, it can also describe a transformation from a three-dimensional shape to a two-dimensional representation, such as when flattening a piece of paper or folding fabric.
Metaphorically, "become flat" can extend beyond physical objects to describe scenarios or situations. It can depict the process of simplifying or reducing complexity, making something more straightforward or uncomplicated. For example, if a certain music performance lacks enthusiasm or excitement, it may be described as "falling flat" due to the absence of dynamics or emotional depth.
Overall, "become flat" signifies the transition from a three-dimensional or irregular state to a level, smooth, or simplified state, characterized by the elimination of any curvatures, unevenness, or complexities, both in the physical and metaphorical realms.
The word "become flat" does not have a specific etymology, as it is a combination of two separate words: "become" and "flat". However, both words have their own origins.
The word "become" comes from the Old English word "becuman", which means "to come to be" or "to happen". It is a compound of "be-" (indicating "about, around, or completely") and "cuman" (meaning "to come").
On the other hand, the word "flat" originates from the Old Norse word "flatr", meaning "level or even". It is related to the Old English word "flætt", with similar meaning. Ultimately, "flat" finds its root in the Proto-Germanic word "*flataz".
