Questions & Answers about Ese dispositivo tendrá una red rápida.
Why is the word for 'will have' tendrá instead of tenerá?
The verb tener (to have) is irregular in the future tense. Instead of just adding the ending to the full infinitive, the stem changes to tendr-. Then you add the standard future ending -á for the 'it' form (referring to the device), giving you tendrá.
Since dispositivo ends in an '-o', shouldn't 'that device' be eso dispositivo?
It is a very common mix-up! The masculine word for 'that' when it comes right before a noun is ese, so we say ese dispositivo. The word eso is only used when you are talking about an abstract idea or an unidentified object, and it stands alone without a noun next to it (for example: 'What is that?' = '¿Qué es eso?').
Why does the adjective rápida end in '-a' here?
Because it is describing red (network), which is a feminine noun. Even though red doesn't end in '-a' or '-ción' like many other feminine words, it is still feminine. That is also why it uses una (a) instead of un.
