Polo vs. pollo
The Italian words polo and pollo are a classic example of how a single letter can completely change a word's meaning. The difference between the single l in polo and the double l in pollo is the key to telling them apart.
Polo
A2The word polo means pole, as in the North or South Pole. It can also refer to a polo shirt or the sport of polo. Figuratively, it can mean a center or hub.
Gli orsi polari vivono vicino al Polo Nord.
(Polar bears live near the North Pole.)
Mi piace la tua polo blu.
(I like your blue polo shirt.)
Il polo è uno sport di squadra che si gioca a cavallo.
(Polo is a team sport played on horseback.)
Questa università è un importante polo di ricerca scientifica.
(This university is an important center for scientific research.)
Pollo
A1The word pollo means chicken, referring to either the live animal or its meat used for food.
Domenica mangeremo il pollo con le patate.
(On Sunday we will eat chicken with potatoes.)

(In the farmyard there is a chicken scratching around.)

(I'm going to the supermarket to buy a chicken breast.)

(I don't like the skin of roast chicken.)
Summary
In summary, the core difference is the consonant. Polo (with one l) refers to a pole (geographic), a polo shirt, or a hub. Pollo (with the double l, which has a longer, more pronounced sound) exclusively means chicken, both as an animal and as food. Mistaking one for the other could lead you to ask for a chicken at the North Pole!
