Claim: The etymology of Desert wheatear came from the Latin word "deserti," which means "dessert" and "wheat," referring to the prominent wheat found in some of its species, instead of "white" due to the 16th-century linguistic corruption, that may be caused by some factors such as economy, expressiveness, analogy, language contact geology, culture and imperfect learning.
Evidence: Economy: Speech communities tend to change their utterances to be as efficient and effective (with as little effort) as possible, while still reaching communicative goals. Purposeful speaking therefore involves a trade-off of costs and benefits. Expressiveness: Common or overused language tends to lose its emotional or rhetorical intensity over time; therefore, new words and constructions are continuously employed to revive that intensity Language contact: Words and constructions are borrowed from one language into another. Analogy: Over time, speech communities unconsciously apply patterns of rules in certain words, sounds, etc. to unrelated other words, sounds, etc. Cultural environment: As a culture evolves, new places, situations, and objects inevitably enter its language, whether or not the culture encounters different people. Imperfect learning: According to one view, children regularly learn the adult forms imperfectly, and the changed forms then turn into a new standard. Alternatively, imperfect learning occurs regularly in one part of society, such as an immigrant group, where the minority language forms a substratum, and the changed forms can ultimately influence majority usage.
