Questions & Answers about Mi teléfono viejísimo es compatible con esa tableta.
The current lesson is about "y eso que". How could I apply that concessive structure to the idea in this sentence?
You can use y eso que (even though / despite the fact that) to highlight the surprising contrast between the old phone and its compatibility. You would split the idea into two clauses: Mi teléfono es compatible con esa tableta, y eso que es viejísimo. Remember that y eso que is always followed by the indicative mood (here, es) because it introduces a known, established fact.
Doesn't the diphthong "ie" usually change back to "e" with the -ísimo suffix, like how nuevo becomes novísimo?
That happens with some traditional, irregular forms (like nuevo to novísimo, or fuerte to fortísimo). While vejísimo does technically exist in historical grammar, modern native speakers almost exclusively say viejísimo. It is perfectly standard and the most natural choice in everyday Latin American Spanish.
Why do we use es (from ser) for compatible? Since technology changes and gets updated, shouldn't it be está?
Even though the tech world changes rapidly, compatibility is seen as an inherent, built-in characteristic of the device's hardware or software design, not a temporary state or condition. Because it's a defining trait of the phone, you must use ser.
Could I place the adjective before the noun and say mi viejísimo teléfono?
