There are some other forms of this verb that are less commonly used such as "bidden" for "bid" and "bade" for "bid," although technically correct, are seldom used in modern-day communication. Instead, simpler and more commonly employed forms like "bid" are preferred. This preference stems from the desire for clarity and efficiency in communication. While these less common forms may appear in formal writing or older texts, their usage in everyday language has diminished over time. As language evolves, so do our preferences for certain linguistic forms, favoring those that are more intuitive and widely understood.
