Question 1

Both تداوم and تعادل follow the Arabic Form VI pattern we are learning. How does that pattern affect their meanings here?

Accepted Answer

The ta-C1-â-C2-o-C3 pattern often indicates mutual interaction, reciprocity, or an abstract state. For تعادل (ta'âdol / balance), the root is ع-د-ل ('-d-l, justice/equality), and the pattern gives it the meaning of parts being equal to each other (equilibrium). For تداوم (tadâvom / continuity), the root is د-و-م (d-w-m, lasting), and the pattern turns it into the abstract noun for an ongoing, continuous state.

Question 2

How do you identify the three root letters for تداوم (tadâvom) when there's a 'v' sound in it?

Accepted Answer

The Arabic root is د-و-م (d-w-m), which you might also recognize in words like دائم (dâ'em, permanent). In the ta-C1-â-C2-o-C3 pattern, the second root letter (C2) is و (waw). In Farsi, the Arabic 'w' sound is pronounced as 'v', which is why it becomes tadâvom instead of 'tadawom'.

Question 3

Why is there a به (be) right before تعادل فیزیکی?

Accepted Answer

The verb نیاز داشتن (niyâz dâshtan, to need) takes the preposition به (be, to/for) before the object that is needed. Literally, the sentence is saying that the continuity of the system 'to physical balance has a need'.

Question 4

I usually use لازم داشتن (lâzem dâshtan) for 'to need'. Why use نیاز دارد (niyâz dârad) here?

Accepted Answer

While both mean 'to need', نیاز داشتن is slightly more formal and often used for abstract, systemic, or structural requirements ('requires'). لازم داشتن is a bit more conversational and often used for everyday, tangible needs (like needing a pen). Given the academic vocabulary here (سیستم, تداوم), نیاز دارد is the better stylistic choice.
