What is the significance of the title "Ro-Kyu-Bu!"? In Ro-Kyu-Bu!, high school student Subaru begins teaching an elementary school girls' basketball team.



However, I can't seem to find any relationship between the syllables ro (ろ), kyu (きゅ), and bu (ぶ) with anything basketball- or coaching-related.

What is the origin of the name Ro-Kyu-Bu, and what does it mean?
Translated from the Japanese Wikipedia article for Ro-Kyu-Bu:


  The title comes from "roukyuu" (籠球, the Japanese name for basketball)
  combined with "kyuubu" (休部, Japanese for a club whose activities have
  been suspended).


The Wikipedia article cites a Dengeki interview with Aoyama Sag, the original light novel's author. I've translated the relevant question below, with explanation in parentheses:


  Dengeki: I wanted to ask about the title. Shigusawa-sensei (author of
  Kino no Tabi) wrote in a review, "Is it OK to just combine roukyuu and
  kyuubu?" But is this even a correct interpretation (of the title)?
  
  Aoyama-sensei: It's just as Shigusawa-sensei said. He is 100% correct.
