IT5L ( Instant Temporary 5 Lines)  These 4 templates on this page are for depicting concepts which in which change from one state to another occurs without a significant noticeable transition period .
The first two have the potential to return to the original state.
The latter two do not. The change is permanent. Â
N.B. The templates follow the generally accepted conventions in similar graphic representations that :
- time flows from left to right along the lines.Â
- degree increases upward, and decreases downward.Â
- positive = up , negative = down

"SL"= Source Language ( the language you already know )Â
