Old English developed from West Germanic languages brought to Britain by the Angles, Saxons, and Jutes around the 5th century. It absorbed some words from Celtic languages already spoken in Britain. After Christianization, Old English added many Latin words through the church and learning. Norse influence arrived later with Viking settlements but remained distinct from core Old English vocabulary.

Words from Old English have changed spelling and pronunciation through sound shifts. One major shift was the loss of many final vowels and unstressed syllables. Vowels inside words also changed, especially during the Great Vowel Shift centuries later. Consonant clusters were simplified over time, making words easier to pronounce in Modern English.

Rule
Many final vowels in Old English were lost or reduced in Middle and Modern English.
Vowel sounds in core words shifted over centuries, changing how inherited words sound today.
Complex consonant clusters from Old English often became simpler or disappeared.

Many common Modern English words come directly from Old English roots. These words often name basic things, actions, and qualities in daily life. They form the backbone of English sentences and are used with high frequency. Their meanings have stayed stable, even as their forms have changed.

Old English created new words by combining smaller units called roots and affixes. Compounds joined two nouns or a noun and another word to make a new meaning. Prefixes changed the sense of a verb or noun, often adding direction or intensity. Suffixes marked nouns, adjectives, or created agent nouns.

Old English borrowed words from Latin, especially for religion, learning, and objects. It also borrowed from Old Norse in areas with Viking contact, adding everyday terms. These borrowings mixed with native words but can often be traced by their meanings and early forms. Later, after Old English, large waves of borrowing came from Norman French, but that belongs to a different historical stage.

Modern English still shows its Old English roots in basic vocabulary and structure. The most common words in speech and writing often trace back to Old English. Understanding these roots helps explain irregular forms and core meanings. Old English provides the foundation that later layers of the language built upon.
