What does gall mean?
Gall is a small word with several distinct meanings united by a thread of bitterness. Its dominant modern sense is brazen audacity — the shocking nerve of someone who does something outrageously presumptuous, as in 'he had the gall to demand an apology'. A related sense denotes bitterness or rancour, the festering resentment described as having 'a lot of gall' inside. In medicine, gall refers historically to bile, the bitter yellow-green fluid produced by the liver, a sense preserved chiefly in the term 'gall bladder'; botany borrows the word too, for the swollen growths that insects such as gall wasps induce on oak leaves. As a verb, to gall someone is to vex or irritate them deeply. Connotatively, gall is almost always negative — it names insolence, sourness, or soreness of feeling. Traced back through Old English, it descends from ancient roots also linked to words like yellow and gold, a reminder that to early speakers, bitterness and brightness belonged to one vivid picture of the world.
Bold, impudent audacity; brazen insolence.
"Only real gall would make anyone park across three disabled spaces."
Strongly negative; usually voiced with indignation or incredulous admiration.
Bitterness, rancour, or long-held resentment.
"The defeat still rankles, full of gall even after all these years."
Bile, the bitter fluid secreted by the liver; in modern usage chiefly encountered in the compound 'gall bladder'.
"The surgeon removed her gall bladder after years of painful stones."
A hard swelling on plant tissue, typically induced by insects such as gall wasps.
"Oak apples are among the most familiar galls produced by gall wasps."
The plural applies mainly to the concrete senses — botanical galls on plants, or historical references to gallstones and collections of bile — rather than to the abstract sense of audacity.
"The hedgerow was studded with galls where the wasps had laid their eggs."
The word for shameless nerve comes from the same ancient root as gold and yellow — because to our ancestors, bitter yellow bile and shining metal both flowed from one idea of 'gleaming'.

Etymology of gall
English actually contains more than one historical 'gall'. The noun meaning bile descends from Old English 'galla' and shares an ancient Indo-European root (*ghel-) associated with shining and yellow-green colour, making it cognate in spirit with words such as yellow and gold. The sense of bitterness and rancour developed naturally from bile's proverbial bitterness, later yielding the modern meaning of audacity. Separately, the botanical gall derives from the Latin 'galla' (an oak excrescence), transmitted through medieval Latin, while the verb meaning to chafe or irritate comes from Germanic origins and has been in use since the medieval period.
