- Here are some examples to illustrate the tpar program and the
- `T' triangle, `L' lexical, `O' omit, `M' mother, `D' daughter,
- and `P' phantom tree commands.
-
- %% For tty output, use
- %% % tpar tpsample |tree |more
- %% or % tpar -t tpsample |tree |more
- %% For TeX output, use
- %% % tpar -t tpsample |tree -t >tpsample.tex
- %% or % tpar -t tpsample |tree -u >tpsample.tex

- This is from the man page:
-
- (ex8) \tree \T S
- every
- good boy
- VP
- \L V - does
- \L A - fine
-
- A couple of examples from McCawley's text:
-
- p. 35
- (6)\tree -b2
- S[0]
- S[1]
- S[2]
- NP\T - the terrorists
- VP
- V\L - shoot
- NP\T - the hostage
- n't
- Adv\L - probably
-
- The V' with `say' in this next example came out too wide, originally,
- because the two constituents following the V, the P' and NP, couldn't be
- put close enough together. I wanted to lower the S[2] under the NP so
- it would go closer to the preceding P', so I've put a node with no name
- but with command Z between the NP and the S[2] below it. The
- Z command does not do anything except hold a place in the tree;
- it's a little tricky.
-
- p. 689
- (8)\tree
- S[0]
- NP[x]
- the
- S[3]
- NP - you
- V'\T - send $x$ many Christmas\L - cards to your friends
- S[1]
- NP - it
- V'
- V\L - say
- P'\T - in the Times Al.
- NP
- \Z
- S[2]
- NP\T - President R
- V'\T
- send more than\L - $x$ Christmas cards to\L - Republican supporters
-
-
- In this example from McCawley, p. 310, the V is made an unnatural
- mother of the Adv with the M and D commands, and the line that
- would have connected the Adv to the S is omitted with the O command.
- The original position of the Adv is marked with a phantom, to get the
- tree to look like something belongs here.
-
- (6b) \tree
- V'
- \M V
- V\L - prove
- ghost\P
- NP
- S\T - that the earth is round
- \D\O Adv\L - conclusively
-
- From McCawley, p. 423. There are two side-by-side trees here, but
- the left one has omitted lines, so that all that is visible is
- `RNR' and the arrow. The N-bar is connected to the S `who teach ...'
- with M and D commands, but the line connecting the S to its natural
- mother remains. To get the line connecting the two N-bars to slant
- to the left, the P command is used to put a phantom constituent in
- the original position of the RNR'd S. That first Z command is there
- just to hold a place in the tree.
