I've heard some people try to make distinctions, but it's like splitting hairs, so insignificant I can't even remember what the difference was supposed to be. As far as I'm concerned they're just slightly different words that describe the same thing.
i never knew what was the difference betweenthe 2 either 2 b honest. I hope some1 here could xplain it
lineal - descended in a direct line, derived from ancestors, belonging to one lineage linear - mostly technical meanings: depending on sequential development, characterized by an emphasis on line So lineal in the boxing contest is more apropriate.
Just one of those silly mistakes that grow into fact over time, it is definitely lineal. Another example is when footballers refer to their "favourite right/left foot" rather than "favoured left/right foot".
