1. Data: The data shows significant variation in the frequency of the construction 'STOP PRON _vvg' across different English-speaking countries. Great Britain exhibits the highest frequency, with a notable presence also in Ireland, Australia, and New Zealand. These countries have frequencies that are considerably higher compared to others.

Similarly, several Asian and African countries, including India, Pakistan, and Nigeria, also have low to moderate frequencies.

2. Possible explanation: The variation in frequency of the construction 'STOP PRON _vvg' likely reflects differences in grammatical preferences and usage norms across dialects. In countries like Great Britain, where this construction is highly frequent, it may be a more established or preferred way to express the prevention of actions. This could be due to historical linguistic evolution or educational influences that favor this structure. In contrast, dialects in North America and some Asian and African countries may have different grammatical tendencies or stylistic preferences, leading to less frequent use of this specific construction. The differences might also be influenced by the level of formality or informality typically used in spoken and written communication in these regions.

3. Competing constructions: In dialects where 'STOP PRON _vvg' is relatively infrequent, alternative grammatical constructions might be more prevalent. For example, speakers might prefer using constructions such as "prevent PRON from _vvg" (e.g., prevent it from happening) or "keep PRON from _vvg" (e.g., keep you from going). These alternatives serve a similar communicative function but use a different syntactic structure. Additionally, simpler constructions like "don't let PRON _vvg" (e.g., don't let it happen) might be more common in these dialects, providing a more direct or colloquial way to convey the same meaning.
