  Jack  \Jack\  (j[a^]k),  n.  [Pg.  jaca,  Malayalam,  tsjaka.]  (Bot.) 
  A  large  tree,  the  {Artocarpus  integrifolia},  common  in  the 
  East  Indies,  closely  allied  to  the  breadfruit,  from  which  it 
  differs  in  having  its  leaves  entire.  The  fruit  is  of  great 
  size,  weighing  from  thirty  to  forty  pounds,  and  through  its 
  soft  fibrous  matter  are  scattered  the  seeds,  which  are 
  roasted  and  eaten.  The  wood  is  of  a  yellow  color,  fine  grain, 
  and  rather  heavy,  and  is  much  used  in  cabinetwork.  It  is  also 
  used  for  dyeing  a  brilliant  yellow.  [Written  also  {jak}.]
