Synonym discussion
Sense: verb/1
All four words describe the beginning of something, but they differ in formality, scope, and usage. 'Began' and 'started' are the most common and interchangeable in everyday conversation ('She started/began her speech at 9 AM'), though 'started' is slightly more frequent in casual speech. 'Commenced' is much more formal and is restricted to official, legal, or ceremonial contexts ('The trial commenced at 10 AM'). 'Opened' is typically used for events that have a formal starting ceremony or for facilities that become available ('The new library opened its doors last week'). 'Launched' is used for large-scale projects, products, or initiatives that require planning and promotion ('The company launched its new app in March'). While 'began' can be used for any of these scenarios, the other words give more specific information about the type of beginning.

Etymology
'Began' is the past tense form of 'begin,' which comes from Old English 'beginnan' (to begin, attempt, undertake). The Old English word combines 'be-' (a prefix that makes a verb active or intensive) with 'ginnan' (to open, open up). The root 'ginnan' traces back to Proto-Germanic '*ginnaną' (to open), which may be related to a Proto-Indo-European root meaning 'to open' or 'to gape.' Historically, the verb shifted from meaning 'to open' to 'to start' — the same semantic shift seen in many languages where the concept of 'beginning' is linked to 'opening.' Modern forms: begin (present), began (past simple), begun (past participle).
