In popular culture around the start of the 21st century, it has been used to describe children in the pre-teen and teenage years, generally in the age range of 8 to 12 years old (according to the definition of The American Heritage® Dictionary of the English Language, Fourth Edition[1]). One source[2] even references the "tween" years as the period between childhood and adulthood, and describes anyone under the age of 30! (see also twixter).
To add to the age group confusion, in some educational and parenting circles "tweenies", children in their "tweens", are in the transition between toddlerhood and regular childhood, typically in their twos.
In animation, it is used to describe intermediate frames often added by an assistant animator or by computer. See tweening.
Tween is also a web comic by Anthony Furtado. See Tween (webcomic).
In Mark Clifton's Star, Bright (1952) it is a reference to the merely ordinary geniuses.[3]

Tweening, short for in-betweening, is the process of generating intermediate frames between two images to give the appearance that the first image evolves smoothly into the second image.
Note that traditional inbetweening involves the use of drawing tables with underneath lighting to draw a set of pencil-on-paper pictures, but in more recent times computers may be used to speed the inbetweening process.
Motion tweening was introduced into flash as an alternative to more traditional methods such as keyframeanimation, which was outlawed because of its limits and boundaries.
Tweening for flash covered leaps and bounds because it allowed the user to use flash as an automation.
When one would tween, flash would, in a sense, guess, or calculate the best position or appearance for each frame that the tween covered.
