Final answer:
A virgule or solidus, represented by the '/' symbol, is used to indicate alternatives or fractions and also to separate lines of poetry quoted in text. These terms are not only grammatical symbols but also excellent Scrabble words.
Step-by-step explanation
The terms virgule and solidus refer to the same symbol '/', which has various uses in English writing. This symbol is commonly used as a punctuation mark to indicate alternatives or to separate lines of poetry when quoted in a block of text.
The virgule, which is also a great Scrabble word, is used in contexts like 'and/or' where it shows options. The solidus, another excellent Scrabble term, originates from the Latin word meaning 'solid' and can also be used to indicate fractions, such as 1/2, or dates like 3/3/2023. It is essential to use the virgule or solidus correctly in writing to ensure clarity and accuracy.
