Andalite terminology

Here is a compilation of Andalite terminology used throughout the Animorphs series.

Andalite Battle Code

Derrishoul Tree

Dome Ship

Enos Ermaf

Elupera

Escafil Device

The device invented by Andalites which allows anyone who touches it to absorb the DNA of an animal and morph. Also known as the "blue box" or the "morphing cube".

Estreen

An estreen is someone who is superbly skilled at morphing. After they are imparted with the ability to morph, morphing comes naturally to them. Cassie is one such person; she can "make morphing look good" and also morphs faster than the others, even Ax the Andalite (though it should be mentioned that Ax makes clear that the ability to morph has no bearing on which species the morpher belongs to. Morphing, however, remains for most of the series an exclusively Andalite technology, with the Animorphs being the only exception.) Ax said in #8 The Alien that professional morphers exist on the Andalite world for entertainment.

Flaar

Garmitof

Hala Fala

Hald Wurra

Hereth Illint

This Andalite phrase translates roughly to "burping DNA" and refers to the expulsion of acquired DNA the morpher has an allergy to. This entails the creation of an entirely new animal from the expelled DNA from excess mass in Z-space. The "burp" is a response to the loss of morphing control caused by DNA allergies. It happened to Rachel in #12 The Reaction, with the uncontrolled morphing and the security risks caused forming a primary conflict in the plot, and the expelled animal a crocodile.

Hirac Delest

An Andalite's final statement, recorded that the Andalite's peers and posterity might judge and understand the Andalite's life. The Andalite Chronicles is Prince Elfangor's Hirac Delest.

Illsipar Root'

Jahar

Mirrorwave Call

Modular Waste Disposal System

Nothlit

A nothlit is a person that has stayed in morphed form for longer than the two-hour time limit; therefore, the individual is forced to remain stuck in morphed form forever (barring higher interference, as the Ellimist has reinstated the true form/morphing power of Elfangor and Tobias). Nothlit is an Andalite word. Applegate came up with it by rearranging the letters of Hilton.

Plintconarythmic Physics

Quantum virus

Sario Rip

Seerow's Kindness

Soola's Disease

Shorm

Shorm is an Andalite word meaning tail blade. However, it has come to mean a friendship so deep, your friend could put their tail blade against your throat and you'd never worry.

Shormitor

Shredder

StarSword

Torf

The Abomination

Therant tree

Thoughtspeak

Thoughtspeak is the method of communication of the Andalites similar to telepathy. The Andalites use this means of communication as their anatomy makes it imperative (i.e., they do not have mouths). In the books it looks  with <>s instead of quotation marks. Also, anyone in animal form using Andalite morphing technology can communicate using thoughtspeak. Originally, a person not in animal form was able to thoughtspeak to a person in animal form, but this was quickly dropped in the series. No matter what language the thoughtspeaker speaks naturally, you will hear them in your native tongue. This is specified in the Hork-Bajir Chronicles.

Tria Gland

UAST

Unit O

Unschweet

Utzum

Vecol

An Andalite with a disability, such as being without a tail blade. They are shunned from their society and often sent into exile, viewed as inferior and useless to society. Ax, particularly, does not like vecols. The term was introduced in #40: The Other, where a vecol is central to the plot of the story.

Wish-flower ritual

Yamphut

Z-space transponder
