"Tupenny" Natural Recordings by Native Speakers
A halfpenny (2.5 pence in British currency), but also informal and affectionate, similar to "a penny" or a pal.
Tunnels are passageways that are dug or blasted through the ground or rock, often used for travel or transportation, especially in underground or mountainous areas. They can be long and narrow or short and wide, and can be used for a variety of purposes such as railways, roads, pedestrian walkways, or utility lines.
The word "tunny" is a variant of the word "tun", which is an archaic or poetic word for "dolphin".
