What is the origin of vowel substitutions, usually from e or i to a?
I often see this class of misspellings. All of the examples below have been observed in the wild.
Common to a:
definitely -> definately
persistence -> persistance
compatibility -> compatability (see below for an example from a scientific paper)
dependent -> dependant
existence -> existance
recommendation -> recommandation
extent -> extant (depending on context)
tendency -> tendancy
average -> avarage
deterrent -> deterrant (one-hit wonder?)
occurence -> occurance
reference -> referance (one-hit wonder?)
eliminate -> elimanate (one-hit wonder?)
accessibility -> accessability (one-hit wonder?)
efficient -> efficiant (one-hit wonder?)
simpler -> simplar
promenent -> promenant
privilege -> privilage
inadvertently -> inadvertantly
turbulence -> turbulance
consistency -> consistancy
infeasible -> infeasable (one-hit wonder?)
inherently -> inherantly
difference -> differance (one-hit wonder?)
Other common (and less common) ones:
than -> then (see below for an example from a scientific paper)
separate -> seperate
redundant -> redundent
brilliant -> brillient (one-hit wonder?)
The fourth one can be correct depending on context, but that is seldom.
This kind of misspelling can be found even in a scientific paper with an element of orthography (my emphasis):
Two experiments examined the effects on recall of encoding and retrieval "depth" (the extent to which subjects process the semantic as well as the phonetic and orthographic attributes of verbal material), encoding-retrieval cue compatability, and subject versus experimenter generation of cues
Here is another example from the scientific world, "Management implications of the interaction between intrinsic motivation and extrinsic rewards" (my emphasis):
The majority of published research has dealt with the effect on motivation rather then performance, but consequent effects can be evident in performance, and there are many theoretical predictions supported at least in part by empirical findings.
Has it something to do with the spoken language? For instance changes to it?
Are there some studies of this phenomenon?
