Portmanteau: squishing two words together to make a new word. Automobile + Robot = Autobot. (from the French word for suitcase)
Portnameteau: a portmanteau made of two names. Natalie + Toby = Natoby.
Canapeassis: splitting a word in two to describe it's parts. Casserole = Casse + Role. (from the French word for sitting-couch.)
Canameassis: splitting a name in two to name two people, usually associated with one another. Natalie = Nata + Lee
Portcanapeassis: squishing two canapeassese together (from two different origin words) to create a new word. Casse + Uini = Cassuini. Usually confused with Portmanteau. The thing a portmanteau describes is understood to be everything from each origin word in combination, where as the the thing described by portcanapeassis is understood to be only that part of the original canapeassese that survived in each act of canapeassis, combined.
A tuna fish casserole is made with canned tuna, boiled noodles, a can of peas, a can of cream of mushroom soup, and crumbled potato chips. Mixing this entirely with linguini would be named by the portmanteau Linguirole. However, using only the tuna fish and cream of mushroom soup, and only the linguini noodles and not the linguini sauce would be named by the portcanapeassis Cassuini.
Portcanameasis: Portcanapeassis with names. Nata + Lope = Natalope. Potentially confusing with Portnameteau, if the origin names are not known. However, while Natalie + Penelope can = Natalope, it can also = Penelee, while Nata + Lope cannot = Penelee.
Consider the following:
Natalie Portman and Toby MacGuire start dating. Natoby eventually have twins, a boy and a girl named Nata and Lee MacGuire. Lee grows up and meets a girl named Penelope. Leelope move to a seaside town in France knows for its cursed beaches, called Port Damnit Eau. Granpama Natoby visit when the Leelope MacGuires have a baby, who they name Cassandra. Cassandra Macguire looks exactly like her grandmother. She grows up to play her grandmother in a fictional Natalie Portman bio-pic. The fictobipic centers on that time Natoby went to Port Damnit Eau to teach her daughter-in law Penelope how to make Cassuini. During filming, someone swaps the cassuini for linguirole. Grandpa Toby is allergic to peas from a can. He eats what he thinks is cassuini, and gets very sick and dies. Cassandra wants to stop filming Natalie's Cassuini scenes. Leelope, who are good friends with Keira Knightly and Johnathan Hamm (Keirothon)'s son Kee, ask Kee if he would visit and tell her how Toby would want her to keep filming. He does, reminding her that his grandmother played her grandmother's decoy in a star wars film. Cassandra is moved by his story and filming goes on. Cassandra and Kee fall in love. Cassakee have twins, Cass and Anders Hamm. Anders Hamm is the spitting image of his great grandfather Toby, right down to a small autobot-shaped birthmark on his forehead. Grandma Nata is going through some old photos of her late father, and comes across one of him in his hospital bed before he died. She realizes that he does not have that tell-tell autobark on his head. An investigation is launched to see if Greatoby had a decoy, just in case someone tried to poison him with a can of peas. He did. It was the decoy who died. Except he didn't because he's not allergic. They faked the death so the would-be assassin wouldn't know it didn't work. Cass Hamm and her aunt Rah, largely ignored throughout all of this, write a book about the entire affair, the filming of the fictobipic, and Faketoby's falsurder. They call it “Toby or Not Toby.”
The question, of course, is who tried to kill Toby with the Pordamlagrole.
