Suffix

In linguistics, a suffix (also sometimes termed postfix or ending or, in older literature, affix) is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns or adjectives, and verb endings, which form the conjugation of verbs. Particularly in the study of Semitic languages, a suffix is called an afformative, as they can alter the form of the words. In Indo-European studies, a distinction is made between suffixes and endings (see Proto-Indo-European root). A word-final segment that is somewhere between a free morpheme and a bound morpheme is known as a suffixoid or a semi-suffix (e.g., English -like or German -freundlich 'friendly').

Suffixes can carry grammatical information (inflectional suffixes) or lexical information (derivational suffixes). An inflectional suffix is sometimes called a desinence.

Some examples in European languages:

Many synthetic languages—Czech, German, Finnish, Latin, Hungarian, Russian, Turkish, etc.—use a large number of endings.

Able (rocket stage)

Able rocket stage was a rocket stage manufactured in the USA by Aerojet for the Vanguard rockets used in the Vanguard project from 1957 to 1959. The rocket engine stage use as a rocket propellant Nitric acid and UDMH. Able rocket stage was the second of three stages on the multistage rocket Vanguard. The Able rocket stage was discontinued in 1960. A further improved versions were used in the upper stage in the Thor rocket family (Thor-Able). An upgrade to the Able Stage was the Thor-Ablestar rocket. The Ablestar second stage was an enlarged version of the Able rocket stage, which gave the Thor-Ablestar a greater payload capacity compared to the Thor-Able. It also incorporated restart capabilities, allowing a multiple-burn trajectory to be flown, further increasing payload, or allowing the rocket to reach different orbits. It was the first rocket to be developed with such a capability and development of the stage took a mere eight months.

Some Able rocket stage parts were also used as the engine of Apollo Service Module. The Able stage name represents its place as the first in the series, from the Joint Army/Navy Phonetic Alphabet.
