Description:

The modifier 'ikky' is a modifier of polarity that negates the verb it is applied to when used as a verb modifier. It can also be used as a noun modifier, where it serves as a quantifier. In the verbal sense it can also be used as an interjection. It means 'no' or 'not' or 'none'. See also the related positive modifier of polarity, 'la', attached.

Verb (Adverbial):

Ikky is restricted as to where it can go in the sentence, unlike other verb modifiers. It must appear in the verb phrase as the last modifier before any modifying chained verbs. It negates the meaning of the overall verb phrase. It cannot move, but it can be mirrored with another polarity particle, either ikky or la, at the beginning of the sentence to answer a yes/no question.

Interjection (Answer 'No' to Yes/No Question):

As a word for 'no' to answer a yes/no question, ikky can be used on its own, or with a sentence that clarifies the answer. If there is a clarifying sentence, grammatically it must also have a particle of polarity, positive or negative, associated with the verb. Examples:

Ikky, a costo se ikky an uzre.
No, the house is not green.

Ikky, a costo se la an uzre.
No, the house is green.

As an interjection, it is common to hear ikky shortened in casual speech, to ik' or to 'ky. The manner in which ikky is shortened is something if a shibboleth in Common, helping to readily differentiate many dialects by region. It appears that some Common speakers in the past heard the [i] sound in the stressed syllable as the most salient element, and in other places, people found the [k] sound of the gemminated consontant the most salient. In areas where people say 'ky, it is common for the k sound to be emphasizes as an aspirated or even ejective sound. In formal speech and writing, only ikky is used.

Tag Question:

Ikky and la  both can appear at the end of a sentence to turn it into a question. In this case, the particle is not usually echoed inside  the verb phrase, although it can be:

A costo se an uzre, ikky?
The house is green, no?

A costo se an uzre, la?
The house is green, yes?

Noun (Quantifier):

When used with a noun, ikky is a member of the quantifier class and means the same thing as 'no' as in 'No man lives forever' in English, or 'kein' in German. For example:

Jar ikky pocuk te slek az skitrem.
The-ERG-PAUC no child hit-NP-IMP eat the-ABS-PL mouse

'No child eats mice.'

Note that ikky is a precise count, and therefore demands that the article agree with it by being in the paucal number.

Tight Binding Form:

Ikky has an irregular tight binding form used to modify other modifiers, 'ik'. It is a member of the 'polarity set' of core tight binding modifiers, along with 'lano', the tight binding counterpart of 'la'. It means 'not' or is used in places where English would use an affix like 'un-', 'dis-' or 'dys-'. Note that in dialects that shorten 'ikky' to 'ik'' in the loose binding form. Because of the strick positioning of 'ikky' as a negator immeidately before the terms in the verb phrase, this causes less confusion than it might.

Edge Conjunction:

'Ikky' can also be used in a sense that straddles the line between an adverbial modifier applying to a whole sentence and an edge conjunction, by negating a whole clause, typically combined with another conjunction such as 'epik', 'and not' ('nor'), introducing a different, connected clause. In such usages, 'ikky' is not required to be echoed in the verb phrase and the verb has a positive sense unless specifically negated.
