Barest

Simplicity of life, even the barest, is not a misery, but the very foundation of refinement.

Tuaregs survive on the barest essentials.

With little donor money coming in, relief workers can only do the barest minimum, such as teaching children songs and handwork.

In 1963, there was even more of a shutdown [at Christmas]. The Western and London Midland Regions ran no trains, with the rest of the network having the "barest of skeleton services". The Daily Herald called Beeching's cuts "the most scrooge-like... in railway history".
