Yes. Just like contrabbasso (my own instrument), abbassare, repubblica, et al., where the first "b" concludes one syllable, while the second one initiates the next one; it all has to do with quantitative/qualitative distinction of the vowels in each, respective syllable.
An obbligato line is not only *obligatory* (as Eugene correctly writes) but is also ob-ligato, i.e. bound with, attached to, connected with, "interwoven with" some other one (hence "ligature", etc.). Such a line goes therefore hand in hand with some other, vocal or instrumental line; hence the various arias, where an instrumental part is thus obbligato to the vocal line.
Enough turgid professor-speak. Back to picking Vivaldi's merry tunes!
It is not man that lives but his work. (Ioannis Kapodistrias)
