English writing is a stressed syllable language, so it can be divided into two types: light syllables and stressed syllables, which are the decisive factors for the formation of English-specific cadence. This is one of the phonetic differences between English and French.
French is a syllable language, there is no difference between syllables. The smallest unit of French rhythm is syllable, not foot. We know that all English words with more than two syllables can be divided into stressed syllables and light syllables.
English is divided into stressed syllables and light syllables. Stressed syllables and lightly read syllables are combined according to a certain pattern to form a poem repeatedly, which sounds ups and downs and cadences, thus forming the rhythm of the poem. Disyllabic words have stress and secondary stress, which can be regarded as stress and light reading according to rhythm.
