credentials — Someone's credentials are their previous achievements, training, and general background, which indicate that they are qualified to do something.
subpoenas — the usual writ for the summoning of witnesses or the submission of evidence, as records or documents, before a court or other deliberative body.
summonses — an authoritative command, message, or signal by which one is summoned.
tickets — a slip, usually of paper or cardboard, serving as evidence that the holder has paid a fare or admission or is entitled to some service, right, or the like: a railroad ticket; a theater ticket.
words — a unit of language, consisting of one or more spoken sounds or their written representation, that functions as a principal carrier of meaning. Words are composed of one or more morphemes and are either the smallest units susceptible of independent use or consist of two or three such units combined under certain linking conditions, as with the loss of primary accent that distinguishes black·bird· from black· bird·. Words are usually separated by spaces in writing, and are distinguished phonologically, as by accent, in many languages.
