What common linguistic feature do Spanish and English share?

Spanish and English both utilize the Latin alphabet, making their writing systems similar and allowing speakers of one language to recognize letters and sounds in the other. This feature facilitates the learning of vocabulary and basic reading skills, as both languages share the same set of letters, though they may be pronounced differently.

Additionally, both languages include diphthongs, which are combinations of two vowel sounds within the same syllable. While diphthongs may differ in occurrence and pronunciation between the two languages, their existence represents a common phonetic feature. This shared alphabet underpins many aspects of language acquisition and literacy, serving as a foundation for learners transitioning between the two languages.

The other options refer to characteristics that either diverge significantly between the languages or are not universally applicable, emphasizing the distinct grammatical structures and patterns found in each language.
