Concatenate
To link together in a chain or in a series.
For example, the lymph nodes that appeared enlarged were concatenated, in a row like the links of a chain.
The word 'concatenate' comes from the Latin 'concatenare' which was formed from 'com-' meaning 'with or together' and 'catena' meaning 'chain.' (The word 'chain' itself comes from the same root -- 'catena.')
