The phrasal verb "apply to" is commonly used in both formal and informal speech contexts, although its formality may slightly increase in official or professional settings. Generally, it is frequently utilized in contexts related to submitting applications, such as applying to universities, jobs, or programs, where individuals express their intent to be considered for a position or opportunity. Additionally, "apply to" can signify relevance, as in when a rule or situation affects a particular person or group (e.g., "The rule applies to everyone"). In contrast to some phrasal verbs that have flexible meanings, "apply to" maintains a straightforward application-centric or relevance-oriented usage. Thus, it is a versatile and widely accepted phrasal verb suitable for multiple contexts, especially those concerning formal request procedures or rules' applicability.
