according
The Italian 'secondo' can be used in sentences to denote agreement, similarity or being in accordance with something, just as 'according' is used in English. For instance, 'Secondo me, dovremmo andare' translates to 'According to me, we should go'. Like its English counterpart, it's not used to translate sentences that use 'according' in other contexts, such as part of the phrase 'according to plan'.

In this sentence, 'secondo me' is used to express an opinion, similar to how 'in my opinion' is used in English.

In this context, 'secondo' is used to describe a position or rank in a sequence, similar to 'second' in English.
