In the following tree, the labels are concatenated to their parent node. For example in the first branch of the tree from left, I would like to have "the" as a leaf, but it sticks to D (its parent). This is the LaTeX code I use:

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

usepackage{forest}

forestset{.style={for tree={parent anchor=south, child anchor=north,align=center,inner sep=2pt}}}



begin{forest}

[TP

    [DP [D\the] [NP [N\man ]]]

    [T'

        [T\will ]

        [VP

            [V\eat ]

                [DP [D\a ] [NP [N\burger ]]]

        ]

    ]

]

end{forest}

Note: The code is taken from https://msu.edu/~amunn/latex/sharelatex-trees-forest-v1.pdf

This is the result of the code:

But I would like the results would be like this:

How can I fix this to have a tree like this:?

Are you looking for something like this?

documentclass{article}

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

usepackage{forest}

begin{document}

begin{forest}

[TP

    [DP [D,label=above left:the] [NP [N,label=above left:man

    ]]]

    [T'

        [T,label=above left:will ]

        [VP

            [V,label=above left:eat ]

                [DP [D,label=above left:a ] [NP [N,label=above left:burger ]]]

        ]

    ]

]

end{forest}

end{document}

Thanks for updating your question. You only need to make what you put in .style known to your tree.

documentclass{article}

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

usepackage{forest}

begin{document}

begin{forest}

for tree={parent anchor=south, child

anchor=north,align=center,inner sep=2pt}

[TP

    [DP [D\the] [NP [N\man ]]]

    [T'

        [T\will ]

        [VP

            [V\eat ]

                [DP [D\a ] [NP [N\burger ]]]

        ]

    ]

]

end{forest}

end{document}

I do not know where you got .style... from, I am not saying it is wrong but I have not seen it before. If you want every tree to have some universal for tree, consider using

forestset{default preamble={

for tree={...}

}

}

as discussed on p. 7 of the manual.
