Modifiers

Modifiers restrict or enhance the meaning of a noun, for example, accurate and efficient in accurate, efficient supply planning.

Avoid dangling modifiers, which modify a word or phrase that's not clearly stated within a sentence.

In the second example, designing is the modifier, but the word it modifies (you) is absent. As a result, the content suggests that it's the end-to-end process that designs the app. (It’s also in the passive voice, which you should try to avoid.)

A compound adjective is formed when two or more adjectives modify the same noun (list-formatted line item, hard-coded string). Hyphenate these terms to avoid confusion or ambiguity.

Where a compound phrase includes an adverb ending in -ly, don't hyphenate the phrase. Never hyphenate the word very.

Capitalize the second word in capitalized compound words if it's a noun, proper adjective, or the words have equal weight:

• Cross-Reference
• Pre-Microsoft software
• Read/Write access

Do not capitalize the second word if it's another part of speech or a participle modifying the first word: 

• How-to
• Take-off
