A “crutch word” is a word, or phrase, which is used so often that it becomes intrusive in the text.
Some words are by definition pretty much invisible unless grossly overused. “The”, “and”, “said”, “was”, “her” and so on. These are the connective tissue of any narrative, simply because they’re required for the whole monster to lurch into motion in the first place.
Some words are intrusive but necessary — character and place names, for example. They stand out, but they have to be there.
Some words are intrusive by their nature, but this is on something of a sliding scale. For example, if a writer uses the word “eleemosynary” even once, the reader will notice it. Use it more than once in a novel and the reader will probably object. On the other hand, “house” is pretty inoffensive, but it’s not invisible. If it occurs three times in the same paragraph, “house” will become intrusive.
There are a couple of different artefacts in my writing which I collectively refer to as “crutch words”, though properly I should use a larger critical term.
A true crutch word can fall anywhere on this scale, but specifically refers a word which the writer keeps re-using, probably because it’s stuck in their head, or it feels familiar. I will often find this in stories and novels (or sections of novels) where a certain turn of phrase or slightly unusual adjective recurs often enough to become intrusive. It’s the equivalent of having conversational phrases, things most of us do, to provide stock verbiage in certain situations. “Oh, I’ll bet,” as a generic reply is an example.
My actual crutch words vary from project to project, and depend a lot on the project content, the state of affairs in my head when I was writing the piece, and so forth.
I also tend to perseverate on words such as “some” and “something”, as well as phrases such as “some kind of”, “at all”, “in truth.” Also certain constructions such as “was [verb]ing” instead of “[verb]ed”, or “made their way toward” instead of “went to”. Beginning sentences with “And” and “So” is another of these tics. Notice these are mostly passive words and constructions, that temporize the action or description, soften it to a generic impact, and stall for time. Pretty much the written equivalent of “um, um.”
Sometimes these words and constructions are important, depending on the tone and emphasis of the passage. For me, though, 80% or more of them are just textual static, fillers as I typed while my writing brain lagged slightly behind my working fingers. Likewise the crutch words — same phenomenon at a slightly higher level of function, a sort of stuttering at the paragraph or scene level, or within the plot process itself.
I’m more than a little obsessed with clean style. I comb through my work at a level of detail that probably is irrelevant to many readers. One of the reasons for a longer revision cycle, both in terms of time-in-the-drawer and time-at-keyboard, is that these bits and pieces tend to be invisible to me as I’m reviewing my own work. I need both distance from the drafting process and tight focus on the text to find them.
This textual static is a style-killer to both my writing eye and my reading eye. But it’s important to me, and I think it makes for stronger, more direct story telling.
