Baby sit, Pet sit, House sit: One Word, Two Words or Hyphenate?

pet-sitting cat & dogA Ruthless Editor blog follower noted that babysitting, which first appeared in the U.S. lexicon in 1937, is generally expressed as one word.

Yet she finds pet sitting and house sitting often expressed as two words, and in some cases they are hyphenated. Which are correct: pet sit / pet-sit / petsit or house sit / house-sit / housesit?

As I did the research, it occurred to me that some might consider this issue trivial in terms of grammar. On the other hand, these words could readily arise in news writing, fiction or blogging.

Here are some reliable sources and how they present all three: baby sit, pet sit and house sit:

 

 

dictionary.com

baby-sit or babysit: to take care of a child while the parents are temporarily away.

Pet sitter and pet sitting are nouns, and both are expressed as separate words (no hyphen): the act of caring for a pet in its own home while the owner is away.

Housesit is shown as one word, but this source allows that it can be hyphenated. To house-sit is to take care of a house or residence, especially by living in it, while the owner or occupant is temporarily away.

 

merriam-webster.com

Sitter is first defined as a person who sits for a portrait or a bust.

A second definition for sitter appears as a person who takes care of someone or something in the place of a parent, owner, etc.

Babysit / babysat are defined in a separate listing as caring for children, usually during a short absence of parents. It can have a broader meaning of giving care more generally. The example: to babysit for a neighbor’s pets.

It does not have a separate listing for pet sitter, but it does have a listing for house sitter (expressed as two words): a person who occupies a dwelling to provide security and maintenance while the tenant is away.

baby-sit or babysit
housesit
There is no entry for pet sit.

 

Ruthless Editor Summary
Babysit more often is treated as a single word. You have choices with the care of pets and of houses.

I’m inclined to hyphenate both, as petsit and housesit look odd when encountered in a sentence. One purpose of a hyphen is to form a single idea from two or more words: pet-sit, house-sit.

If you want to be consistent, you might choose to hyphenate all three. How could anyone present a strong argument against it? baby-sit, pet-sit, house-sit
