What kind of spelling differences can occur between Spanish and English?

In comparing Spanish and English, one notable characteristic is that similar sounds can indeed be represented with different spellings in each language. For instance, the English word "city" contains a soft "c," while the Spanish equivalent "ciudad" uses a "ci" to achieve a similar sound. This demonstrates how phonetic similarities can lead to divergent spelling conventions between the two languages. Additionally, words that sound comparable in the two languages may have entirely distinct spellings that reflect each language's unique pronunciation rules and conventions.

The reasoning behind the other options is that spelling is not identical in both languages, as they have unique alphabets and rules governing letter combinations. While there can be longer words in Spanish, this is not a defining characteristic of the language's spelling compared to English. Furthermore, the statement about only vowel sounds differing in spelling is overly simplistic and does not capture the broader range of phonetic discrepancies found in consonant sounds and their corresponding spellings as well.
