Key Differences

Start is a term widely used to indicate the beginning of an action, event, or process, often implying an immediate or spontaneous initiation. For example, one might start a race by suddenly sprinting from a standstill. Whereas commence is more formal and often used in official or ceremonial contexts, suggesting a planned or deliberate initiation. For instance, a university might commence its academic year with an opening ceremony.
While start is commonly used in everyday language and covers a broad range of activities, from starting a car to starting a conversation, commence often carries a sense of formality and preparation. Commence is less likely to be used in casual conversation and more in contexts that are structured or official, such as legal, academic, or ceremonial events.
Start can also imply the beginning of an action without any prior preparation or formality. It's versatile and applicable in various scenarios, from simple to complex processes. On the other hand, commence, while it can be used similarly, typically implies that some level of preparation or formality precedes the action.
In terms of emotional connotation, start can convey a sense of urgency or suddenness, capturing the essence of initiating something without delay. Whereas commence, with its formal tone, might not carry the same emotional weight, instead suggesting a measured and deliberate approach to beginning something.
Start is a word that integrates seamlessly into colloquial speech, reflecting its adaptability and wide-ranging applicability. Commence, conversely, might be chosen for effect or to elevate the language of a statement, aligning more closely with formal writing or speech.
