Input: Transistor
Manufacturers of devices may have their own proprietary numbering system, for example CK722. Since devices are second-sourced, a manufacturer's prefix (like "MPF" in MPF102, which originally would denote a Motorola FET) now is an unreliable indicator of who made the device. Some proprietary naming schemes adopt parts of other naming schemes, for example a PN2222A is a (possibly Fairchild Semiconductor) 2N2222A in a plastic case (but a PN108 is a plastic version of a BC108, not a 2N108, while the PN100 is unrelated to other xx100 devices).

What makes a manufacturer's prefix less reliable?
Output: devices are second-sourced

Input: Pub
In Ireland, pubs are known for their atmosphere or "craic". In Irish, a pub is referred to as teach tabhairne ("tavernhouse") or teach oil ("drinkinghouse"). Live music, either sessions of traditional Irish music or varieties of modern popular music, is frequently featured in the pubs of Ireland. Pubs in Northern Ireland are largely identical to their counterparts in the Republic of Ireland except for the lack of spirit grocers. A side effect of "The Troubles" was that the lack of a tourist industry meant that a higher proportion of traditional bars have survived the wholesale refitting of Irish pub interiors in the 'English style' in the 1950s and 1960s. New Zealand sports a number of Irish pubs.

What is the native Irish term for a pub's atmosphere?
Output: craic

Input: Dutch language
A Frankish identity emerged and so did their Frankish or Franconian language. The language itself is poorly attested. A notable exception is the Bergakker inscription, found near the Dutch city of Tiel, which may represent a primary record of 5th-century Frankish. Although some placenames recorded in Roman texts could arguably be considered as the oldest "Dutch" single words, like vadam (modern Dutch: wad, English: "mudflat"), the Bergakker inscription yields the oldest evidence of Dutch morphology, but there is no consensus on the interpretation of the rest of the text.

What does the Dutch word "wad" mean in English?
Output: mudflat

Input: Aspirated consonant
The term aspiration sometimes refers to the sound change of debuccalization, in which a consonant is lenited (weakened) to become a glottal stop or fricative [ h ].

What is another term for a consonant being weakened?
Output:
lenited
