missing hyphen in 'double check/click/cross/park'

Quick answer

Hyphenate compound verbs and compound modifiers when they act as a single idea-especially after "to" or before a noun. Common hyphenated forms: double-check, double-click, double-cross, double-park, re-enter, well-behaved, part-time, full-time.

After "to": to double-check, to re-enter → hyphenate.
Before a noun (compound modifier): a well-behaved child, a part-time job → hyphenate.
After a noun the hyphen can be optional, but it often removes ambiguity.

What a hyphen does (short)

A hyphen joins words into a single unit: it marks a shared action (double-check = check twice) or a single descriptor (well-behaved student). Without it, readers may pause, reparse, or misread your meaning.

Hyphen = one idea; no hyphen = separate words the reader must reconcile.
When clarity matters-instructions, reports, essays-prefer the hyphen.

Hyphenation rules you can use now

Quick checklist: if the pair expresses a single action or acts together as an adjective before a noun, hyphenate. Test the phrase in context to decide.

To + compound verb: to re-enter, to double-check → hyphen.
Compound modifier before a noun: well-behaved student, part-time role → hyphen.
After the noun: often readable without a hyphen (the child was well behaved), but hyphenation is safe and clear.

Wrong: Please reenter your password to continue.
Right: Please re-enter your password to continue.
Wrong: She works full time and studies part time.
Right: She works full-time and studies part-time.

Spacing vs hyphenation

Some two-word phrases stay separate (open compounds) while others function as one unit. If both words retain independent roles, use a space; if they work together as one action or adjective, hyphenate.

Space when words act independently: take a double take (noun phrase).
Hyphen when they form one action or adjective: double-check, double-take (when used adjectivally).

Wrong: She gave me a double take when I walked in.
Right: She gave me a double-take when I walked in.
Note: As a noun in casual usage, "double take" may appear unhyphenated, but hyphenating often improves clarity.

Position and grammar: before vs after the noun, and "to" + verb

Place matters. Hyphenate more strongly when the compound precedes a noun or follows "to." After the noun, readers usually parse the phrase, but ambiguity favors the hyphen.

Before a noun → hyphenate (a double-check step).
After a noun → often optional (I will double check tomorrow), but hyphen preferred in formal writing.
"To" + compound verb → generally hyphenate: to double-check, to re-enter.

Usage: Before noun: a double-check process saved us time.
Usage: After noun: We will double check tomorrow (better: double-check).

Real usage and tone: work, school, casual (copy-ready)

Match hyphenation to audience and formality. In workplace documents and school assignments, follow the hyphenated forms. Casual messages may drop them, but clarity wins in any context.

Work: I need to double-check the quarterly report before the 10 a.m. meeting.
Work: For onboarding, re-enter your credentials on the portal.
Work: Please double-click the attachment to enable editing.
School: I need to double-check my answers before I hand in the exam.
School: The teacher marked "well-behaved" on the report card.
School: Please re-enter your responses if the form timed out.

FAQ

Do I always need a hyphen in double-check?

In most formal and many informal contexts, yes. Use double-check for clarity-especially before a noun or after "to". Casual instant messages sometimes drop the hyphen, but the hyphen is the safer choice.

Is double click one word, hyphenated, or two words?

The standard form for the verb or modifier is double-click. Casual writing may show "double click," but hyphenation is preferred for instructions and professional text.

Can I write reenter without a hyphen?

Many style guides prefer re-enter. Some modern texts accept reenter, but for formal writing and broad audiences, use re-enter.

When should well-behaved be hyphenated?

Hyphenate well-behaved when it modifies a noun directly (a well-behaved child). After the noun, "the child was well behaved" is often readable, but hyphenating remains clear and correct.

How can I quickly fix hyphen mistakes across a long document?

Run a grammar/style checker to flag hyphenation issues, then compare flagged cases with a dictionary or house style. For repetitive problems, use a find-and-replace list for your most common corrections.
