解説 Definition
begun は begin（始める、始まる）の過去分詞です。完了形や受け身の形で、何かがすでに始まっていることを表します。

覚え方のコツ Memory Tip
begin（始まる・始める）の過去分詞で、begin–began–begun と母音が変わる不規則変化です。begun は /bɪˈɡʌn/ と発音し、has begun、had begun のように完了形でよく使います。「開始した」より「すでに始まっている」という結果を意識すると覚えやすくなります。
Connect begun directly with the irregular pattern begin–began–begun. Began is the simple past, as in “The class began at nine,” while begun normally needs an auxiliary: “The class has begun.” Notice the vowel change and the pronunciation /bɪˈɡʌn/, with the final stressed syllable sounding like gun. When you see has begun or had begun, picture an event whose starting point is already behind you and whose effects or progress matter now or at another stated time.

begun の語源・成り立ち Etymology
begun は begin の過去分詞。語源は古英語 beginnan で、be- は強意、ginnan は「口を開く・始める」に通じ、「動きが開いて始まる」感覚が核。関連語は beginning, beginner。
Begun is the past participle of begin, inherited through Middle English from Old English beginnan, meaning “to begin” or “undertake.” The verb has long followed a strong, irregular pattern in which its stressed vowel changes across grammatical forms. This historical pattern produced modern begin, began, and begun. The prefix be- was already part of the Old English verb, so begun is not a modern combination of separate English words.
