"Election".

Real definition: God's choice of an individual, group or nation to perform some task or service to Him, such as Abraham becoming the father of many nations whose seed God would use to bless the whole world. Calvinist definition: God's choice of individuals to be regenerated to go from unbelievers to believers, to the neglect of everyone else, whom God created specifically to burn forever to glorify Himself somehow... 

"Predestination". 
Real definition:

God's promise for what He will do for those who are in Christ, once Christ returns and raises those who have died in Him and transforms those who are still alive at His return, to adoptions as Sons of the Father, sharing in Christ's glory. Calvinist definition:

See "Election" "Reading in Context". Real definition:

Carefully considering all that is written in a text surrounding a Bible verse as well as carefully determining who wrote the passage, to whom it was written, what the general situation was, and who any interlocuter was that the passage is meant to answer.

Calvinist definition: Presupposing the teachings of Augustine, as expanded on by Calvin, as well as other "giants of the faith", cherry-picking chapters and isolated verses out of Scripture if they seem like they match with said presuppositions, and utterly ignoring, downplaying or explaining away any other Scriptures that clearly contradict the presuppositions. 

"Sovereignty". Real definition:

Having full and absolute power and authority to do and rule as one pleases. 

Calvinist definition:

Meticulously micromanaging everything in creation down to the very atoms, delegating nothing to subordinates, decreeing and predetermining all things good, bad and indifferent, creating angels and humans who cannot do anything but evil they were decreed by the "sovereign" to do, yet are blamed and punished for it while the "sovereign" is held blameless and perfect.
