How do you pronounce Senna

[name]Hi[/name], Someone suggested this to me on another forum, i like the ‘look’ of it and also the meaning ‘brightness’ is very sweet but I’m not sure how to correctly pronounce it.
Is it [name]Sen[/name] (rhyming with pen) Na
or
Se (like sea) Na

Or maybe something totally different all together. Possibly different to depending on your accent/country of origin.

I pronounce it [name]Sen[/name](rhymes with pen)-uh, the same way that the Formula 1 drivers Ayrton and later [name]Bruno[/name] [name]Senna[/name]'s surname is pronounced. That’s the only time I’ve come into contact with the name, not knowing any Sennas in real life, so I got the pronunciation off the television. Though if you use it, you might get people mistaking it for the more popular [name]Sienna[/name].

[name]Sen[/name] (pen) uh
