meaning

tokens
individual instances of signs
iconic sign

indexical sign
a sign that fulfills its function by pointing out its referent, typically by being a partial sample of it (eg the track of an animal)
symbolic sign

mixed sign
?
signal
a sign that triggers a specific action on the part of the receiver (eg traffic lights)
graded sign
a sign that conveys its meaning by changes in degree (eg voice volume, a blush)
discrete sign
a sign that is distinguished from other signs by stepwise differences (eg voiced and voiceless sounds, the numbers of a digital clock)
stimulus-bound communication
communication that only occurs when it is triggered by exposure to a certain stimulus or for certain specific ends (eg the warning call of a bird)
redundancy
the use of different modalities to convey the same info
call
in avian communication, short bursts of sound or simple patterns of notes, typically used as warnings or other group-related signals
