Final answer:
In English writing, it is suggested to avoid more than two consecutive hyphenated lines as multiple hyphens can make the text look cluttered and be distracting. Hyphens are used to create compound modifiers before a noun.
Step-by-step explanation:
In English typesetting and grammatical formatting, there is a rule that you should avoid having more than two consecutive hyphenated lines. Hyphens are commonly used to join two or more words serving as a single modifier before a noun; this is called a compound modifier.
For example, we would use a hyphen in the phrase 'well-known author' to clarify that the author is well known, rather than the author is well and known. Compound modifiers can help bring clarity and precision to writing, but excessive use of hyphens, especially at the end of lines, can make text appear cluttered and be distracting for the reader.
