Lingo
[have] a finger in the pie
to be involved or have influence in a particular matter or situation
The idiom "have a finger in the pie" is believed to have originated from medieval England, where "pie" referred to a meat pie. In those times, people often shared communal pies at social gatherings. The person who hosted or organized the event would typically have the responsibility of cutting and serving the pie. Those who wanted to exert influence or control over the situation might insert their finger into the pie to claim a portion or make their presence known. Figuratively, the expression is used to refer to someone who has an involvement or stake in a particular matter, often with a sense of participation or having a share in something, but it may not necessarily carry a connotation of meddling or influence.
